Our ROC Just Got Some Major Love from Concealment Magazine
When One of the Industry's Top Publications Features Your Product, You Know You're Doing Something Right
We've got some pretty exciting news to share with you all. Our Revolver Optic Conversion (ROC) was just featured in Issue 47 of Concealment Magazine by Recoil, and we couldn't be more stoked about it.
If you're not familiar with Concealment Magazine, it's one of the most respected publications in the concealed carry world. So yeah, this is kind of a big deal for us.
Why We Built the ROC in the First Place
Here's the thing about J-frame revolvers—they're awesome carry guns. Reliable, compact, simple to operate. But let's be honest: those tiny iron sights can be tough to use, especially in less-than-ideal lighting or if your eyes aren't what they used to be.
For years, if you wanted to put a red dot on your J-frame, you were pretty much out of luck. Your options were limited to expensive custom gunsmithing that permanently modified your gun, or... well, that was basically it.
Now there's a better way.
The ROC: Red Dots for Revolvers, No Gunsmith Required
The Revolver Optic Conversion is our answer to a problem that's been bugging revolver enthusiasts for years. It's a precision-machined mounting system that lets you install a micro red dot sight on your Smith & Wesson J-frame without any permanent modifications.
No drilling. No milling. No sending your gun off to a smith for weeks. Just a solid, reliable mounting platform that you can install yourself and remove whenever you want.
The best part? Your revolver goes back to 100% stock configuration if you ever decide to take the ROC off. It's perfect whether you're a collector who wants to preserve originality or just someone who likes having options.
What Makes It Work
We machine every ROC from aerospace-grade 7075-T6 aluminum—the same stuff used in aircraft and military applications. It's incredibly strong but keeps the weight down, which matters when you're talking about a carry gun. The Type II anodized finish gives you solid wear and corrosion resistance.
The system comes with everything you need: the main conversion bracket, precision side spacers, and all the mounting hardware. We offer it in two footprint options—RMRcc and RMSc—so you can run the most popular micro red dots on the market.
And yes, it works with the Phlster City Special holster, so you can actually carry your optic-equipped wheelgun concealed.
Why Red Dots on Revolvers Actually Make Sense
Look, we get it. There's something beautifully simple about a revolver with iron sights. But there's also something incredibly practical about having a bright, easy-to-acquire red dot when you need to make an accurate shot under stress.
Red dots give you:
- Way faster target acquisition (huge in a defensive situation)
- Better accuracy, especially at distance
- Improved visibility in low light
- An easier sight picture for those of us whose eyes aren't getting any younger
If you carry a J-frame as a backup gun or EDC, these advantages are hard to ignore.
Designed, Engineered, and Built Right Here
Like everything we make, the ROC is designed, engineered, and manufactured in the USA. We're not just slapping our name on something made overseas—we control every step of the process to ensure you get a product that actually works and lasts.
Check It Out
We're honored that Concealment Magazine recognized the ROC and what we're trying to do with it. If you've been thinking about modernizing your J-frame without permanently modifying it, now's a great time to check out what the ROC can do.
Head over to shieldarms.com/revolver-optic-conversion-roc to learn more, or swing by Recoil's website to grab Issue 47 of Concealment Magazine.
Thanks for the continued support, everyone. We've got more cool stuff in the pipeline, so stay tuned.

Shield Arms Weekly Deals: Up to 43% Off | October 16-23
If you've been eyeing Shield Arms gear, this is your week. We're talking serious discounts across our most popular products—from the legendary S15 Combo Pack that transforms your Glock 43X into a higher-capacity carry gun, to premium magazine extensions that'll have you rethinking your entire magazine lineup. Whether you're a Glock carrier looking to maximize capacity without sacrificing concealability, a CZ enthusiast ready to boost your firepower, or someone who just needs a rugged sling bag that can handle anything, this week's Shield Arms weekly deals deliver.
These aren't clearance items or last year's inventory—this is top-tier, Made in USA gear backed by our Lifetime Warranty. And with savings ranging from 23% to 43% off, you're getting flagship performance at prices that make stocking up a no-brainer. But fair warning: these deals vanish on October 23rd, so let's dive into what's on the table.
Featured Shield Arms Discount Deals This Week
The Capacity Game-Changer: S15 Combo Pack 1 (Save $36)
Let's start with the big one. The S15 Combo Pack 1 drops from $122 to just $86—that's a $36 savings on what might be the single best upgrade you can make to your Glock 43X or 48. Here's what you get: three S15 Gen 3 magazines (15 rounds each) plus the steel mag catch you need to run them reliably.
Think about that for a second. You're going from 10 rounds to 15 rounds while keeping that flush-fit, concealable profile. No bulky extensions, no printing through your shirt—just 50% more capacity in the exact same footprint. For anyone serious about concealed carry, this is the kind of upgrade that changes your entire carry philosophy. You're getting everything you need in one package, and at $86, you're paying less than $22 per magazine. That's an absolute steal for American-made steel mags with a Spring for Life Guarantee.
Your New Favorite Carry: The Bang Bag (43% Off)
From $149 down to $85, the Bang Bag is seeing the deepest discount of the week at 43% off. This isn't your typical tactical sling—it's inspired by WWII gas mask bags but built for modern EDC, range trips, and outdoor adventures. The laser-cut MOLLE panels give you modular storage options, the magnetic closure means quick access without fumbling with buckles, and the whole thing is made right here in Montana.
If you've been carrying a backpack to the range or stuffing your pockets with gear on hikes, the Bang Bag solves that problem elegantly. It's big enough to matter but low-profile enough for daily carry. At $85, this is the kind of purchase that makes you wonder why you waited so long.
Glock 43 Owners: The Z9 Magazine is $20 (Nearly Half Off)
The Z9 Magazine for Glock 43 drops from $37 to $20 this week—that's 46% off. This steel magazine gives your G43 nine rounds (up from six) without changing your grip or adding bulk beyond a standard pinky extension. If you carry a Glock 43 and you've been living with 6+1, this is your wake-up call.
At $20, you can afford to grab two or three and always have backups. These are proper steel magazines with the same build quality and lifetime warranty as everything else Shield Arms makes. For the price of a couple boxes of ammo, you're getting 50% more capacity in your carry gun.
AR Magazine Extensions: Boost Your PMAG Capacity
If you run Magpul PMAGs, we've got two stellar deals on pre-installed magazine extensions. Both the standard PMAG Gen3 +5 and the PMAG Gen3 Window +5 are marked down from $51.99 to $40—that's $11.99 off each.
These come pre-installed, so you're getting a complete 35-round magazine ready to run. The billet aluminum extension features an easy-access floor plate for maintenance, and the Window version adds visual round verification so you always know your count. Both are precision-made in the USA and covered under Shield Arms' lifetime warranty. At $40, you're paying barely more than a standard PMAG, but you're getting 35 rounds instead of 30. Stock up for range days, competition, or just because having extra capacity never hurt anyone.
Glock Magazine Sale: 19/23 Extensions for $29
The Glock 19/23 +5/4 Magazine Extension is on sale for $29, down from $39.99. This premium aluminum extension adds five rounds to your 9mm Glock 19 mags (or four rounds to .40 S&W Glock 23 mags), giving you 20 rounds total in a compact package.
These aren't flimsy polymer extensions—Shield Arms machines these from solid aluminum right here in the USA. They're built to last, they're precision-fitted, and they come with the same lifetime warranty as every Shield Arms product. Whether you're building competition mags, truck guns, or just want more capacity for range training, $29 is a no-brainer price point.
CZ Magazine Extensions: Three Models, One Great Price
CZ shooters, we haven't forgotten about you. Three different magazine extensions are all marked down from $39.99 to $27 this week, giving you 32% savings across the board:
The CZ P10S +5 Extension transforms your subcompact into a 15-round carry gun—that's full-size firepower in a concealed carry package. Perfect for those who want more capacity without jumping to a larger frame.
For full-size CZ fans, the P10F/P09 +5/4 Extension adds five rounds in 9mm or four in .40 S&W. You're looking at serious magazine capacity with drop-in installation and zero reliability concerns.
And the P10C/P07 +5/4 Extension does the same for compact CZ models—boosting capacity while maintaining the quality and reliability CZ shooters demand.
All three are precision-machined aluminum, all three install in minutes, and all three are backed by Shield Arms' lifetime warranty. At $27 each, you can afford to upgrade your entire magazine collection.
Why Shield Arms Firearms Accessories Stand Apart
Here's the thing about buying Shield Arms gear on sale: you're not sacrificing quality for price. Every single product in this week's deals comes with our Lifetime Warranty. If something breaks, we replace it. No questions, no time limits, no fine print.
For magazines and magazine extensions, you're also covered by our Spring for Life Guarantee. Magazine springs wear out over time—that's just physics. But with Spring for Life, we'll replace your magazine springs free for as long as you own the product. That means the magazines and extensions you're buying this week at discount prices will keep running for decades.
When you factor in the warranty coverage on top of these sale prices, you're getting flagship-quality gear with lifetime support at prices that most companies charge for entry-level products with zero warranty. That's the Shield Arms difference.
Don't Miss These Deals—They End October 23rd
These weekly deals disappear fast, and this batch ends on October 23rd. Whether you're grabbing the S15 Combo Pack to revolutionize your Glock 43X carry, snagging magazine extensions to boost capacity across your collection, or picking up that Bang Bag for your next adventure, now's the time to move.
Check out the complete lineup at our weekly deals page, and remember—these prices won't last. We'll be back next week with a fresh batch of discounts, so bookmark the page and check back regularly. Your wallet (and your range bag) will thank you.

Why Most Magazine Extensions Fail (And How to Choose One That Won't)
Magazine Extensions for Glock: Why Most Fail & How to Choose Reliable Ones [2025 Guide]
Quick Answer: What Makes Magazine Extensions Fail?
Most magazine extensions fail due to three critical issues:
- Poor attachment systems - Inferior components with inadequate securing mechanisms
- Maintenance complexity - Designs requiring complete removal and special tools for basic cleaning
- Manufacturing shortcuts - Lack of precision machining and quality control
Solution: Look for CNC-machined billet aluminum construction, removable floor plate designs, and lifetime warranties. Quality extensions use precision manufacturing, tool-free maintenance access, and multiple securing mechanisms.
In This Guide:
If you've ever had a magazine extension fall off during training, come loose during competition, or require a PhD in mechanical engineering just to perform basic maintenance, you're not alone. The magazine extension market is flooded with products that look similar but perform drastically differently. As manufacturers who've spent years engineering solutions to these exact problems, we're breaking down what separates reliable Glock magazine extensions from expensive disappointments.
The Hidden Problems With Most Magazine Extensions
Problem #1: Extensions That Don't Stay Put
The most catastrophic failure isn't a malfunction—it's when your extension separates from your magazine entirely. We've seen this happen during matches, training sessions, and unfortunately, when reliability matters most.
Why It Happens:
- Inferior materials construction with inconsistent tolerances
- Stamped components that deform under stress
- Inadequate securing mechanisms that rely on friction alone
- Poor quality control during manufacturing
The Engineering Solution:
Precision-machined billet 6061 aluminum construction ensures consistent tolerances and superior strength. Starting with solid aluminum blocks allows for precise thread engagement and secure mechanical attachment. Type 2 anodizing provides additional durability and corrosion resistance.
Problem #2: Maintenance Nightmares
Magazine maintenance should be straightforward, but most aftermarket magazine extensions turn a 30-second task into a 10-minute ordeal requiring special tools and risking component damage.
Common Maintenance Issues:
- Extensions that must be completely removed to access internals
- Components that require specialty tools for disassembly
- Springs and followers that launch across the room during cleaning
- Risk of cross-threading during reassembly
The Design Innovation:
A removable floor plate system revolutionizes maintenance accessibility. Instead of removing the entire extension, users can quickly access springs and followers through an easy-access panel. This design allows for rapid field maintenance without tools while maintaining structural integrity. Our design is often copied, but never equaled.
Problem #3: Inexperienced Manufacturing
Many companies treat pistol magazine extensions as simple add-on products rather than precision mechanical components. Years of actual manufacturing experience reveals problems that aren't apparent from CAD drawings.
Experience-Driven Improvements:
- Understanding spring dynamics under various load conditions
- Recognizing follower geometry impacts on feeding reliability
- Identifying stress concentration points that cause failure
- Developing proper surface treatments for long-term durability
What Makes a Magazine Extension Actually Reliable
Secure Mechanical Attachment
Reliable magazine extensions use multiple securing mechanisms rather than depending on single points of failure. Properly designed systems include:
- Mechanical threads with precise tolerances
- Index cuts for improved grip during installation and removal
- Positive locking mechanisms that prevent loosening under recoil
- Material compatibility between extension and magazine body
Accessibility-Focused Design
The best magazine extensions are designed for real-world use, not just initial installation. Key features include:
- Tool-free maintenance access for spring and follower service
- Captured components that don't scatter during disassembly
- Clear visual indicators for proper installation
- Compatibility with aftermarket magazine accessories
Manufacturing Quality Standards
Precision manufacturing isn't just about tolerances—it's about consistency across every component:
- Billet aluminum construction provides superior strength and consistency
- CNC machining ensures repeatable dimensions and surface finish
- Type 2 anodizing offers durability and corrosion resistance
- Quality control testing of every component before shipping
Best Magazine Extensions by Glock Model
Glock 19 Magazine Extensions
The Glock 19 is the most popular platform for magazine extensions, with options adding +2 to +5 rounds. Look for extensions that maintain the compact profile while adding capacity. The 15-round factory magazine can extend to 17-20 rounds depending on extension design.
Recommended: Shield Arms Glock 19 +5 Extension - Adds 5 rounds to standard Glock 19 magazines, bringing total capacity to 20 rounds. Features CNC-machined billet aluminum construction with removable floor plate design.
For immediate use without installation: Glock 19 +5 Pre-Installed Extension - Complete magazine with extension already installed and function tested.
Glock 17/22/45/19X/34/35 Magazine Extensions
Full-size Glock 17 extensions typically add +2 to +5 rounds to the 17-round capacity. These extensions are popular for competition use where capacity matters more than concealability.
Recommended: Shield Arms Glock 17 +5 Extension - Increases Glock 17 capacity from 17 to 22 rounds. Precision-machined with tool-free maintenance access.
For immediate use without installation: Glock 17 +5 Pre-Installed Extension - Ready to use out of the box with lifetime warranty coverage.
Glock 26 Magazine Extensions
Subcompact Glock 26 extensions often add +2 to +3 rounds while improving grip purchase. These extensions can transform the 10-round capacity to 12-13 rounds while maintaining reasonable concealability. The Shield Arms Glock 26 +5 Mag Extension adds 5 rounds, bringing capacity to 15 total.
How to Install a Magazine Extension: Step-by-Step Guide
Tools Required
- Magazine disassembly tool or small punch (for some designs)
- Snap caps or dummy rounds for function testing
- Optional: Small container to hold small parts
Installation Steps
Installation is simple and only takes a few minutes. Here's a video that shows the basic steps.
💡 Pro Tip: Quality magazine extensions with removable floor plates allow future maintenance without repeating the full installation process. This design feature saves time and reduces wear on components during routine cleaning.
Maintenance Best Practices
Cleaning Frequency
Clean magazine extensions every 1,000 rounds or quarterly, whichever comes first. For competition or duty use, inspect before each training session or match.
Quick Maintenance Procedure (Removable Floor Plate Design)
- Remove floor plate without tools
- Inspect spring for deformation or damage
- Wipe follower and spring with clean cloth
- Check for debris or carbon buildup
- Apply light lubrication to spring (optional)
- Reinstall floor plate and function test
What to Inspect
- Thread engagement integrity
- Base plate security
- Spring tension consistency
- Follower wear patterns
- Magazine body cracks or deformation
- Anodizing wear or corrosion
The Warranty Question: Confidence vs. Coverage
A manufacturer's warranty terms reveal their confidence in their product's reliability. Short warranty periods often indicate expected failure rates, while comprehensive coverage demonstrates engineering confidence.
Warning Signs:
- Warranties voided by normal use or maintenance
- Coverage limited to specific failure modes
- Exclusions for "wear items" on what should be durable components
Quality Indicators:
- Comprehensive lifetime warranties covering all failure modes
- Coverage that includes normal use and maintenance
- User-serviceable designs that don't void warranties
- Manufacturer backing that extends beyond initial purchase
Making the Right Choice: Complete Buying Guide

The Engineering Difference
At Shield Arms, we approach magazine extensions as precision mechanical components, not simple accessories. Our removable floor plate design emerged from years of customer feedback about maintenance difficulties. Our lifetime warranty reflects confidence earned through extensive testing and real-world use.
Every design decision prioritizes long-term reliability over short-term cost savings. From billet aluminum construction to Type 2 anodizing, each manufacturing step focuses on preventing the failure modes we've observed in competitive products.
Magazine extensions might seem like simple products, but proper engineering makes the difference between accessories that enhance your firearm's capability and expensive frustrations that fail when you need them most.
Frequently Asked Questions About Magazine Extensions
What is the most reliable magazine extension for Glock pistols?
The most reliable Glock magazine extensions feature CNC-machined billet aluminum construction, removable floor plate designs for tool-free maintenance, and positive mechanical locking systems. Look for extensions with lifetime warranties. Shield Arms magazine extensions are engineered specifically for reliability with precision manufacturing and comprehensive warranty coverage.
How much capacity does a magazine extension add?
Magazine extensions typically add 2-5 rounds depending on the pistol model and extension design. Glock 19 extensions commonly add +5 rounds (increasing capacity from 15 to 20), while Glock 17 extensions add +5 rounds (from 17 to 22 rounds). The exact capacity increase depends on spring length, follower design, and extension height.
Do magazine extensions affect reliability?
Quality magazine extensions do not affect reliability. However, poorly designed extensions with inconsistent tolerances, weak springs, or improper follower geometry can cause feeding failures. Premium extensions with precision manufacturing maintain or improve reliability while increasing capacity. Always function test thoroughly with dummy rounds and live fire before relying on extended magazines.
Can I install a magazine extension myself?
Yes, most quality magazine extensions are designed for user installation without gunsmithing. Look for extensions with removable floor plates that allow tool-free access. Installation typically involves removing the magazine base plate, installing the extension, and reassembling with the new spring and follower. The process takes just a couple minutes per magazine. Always function test with dummy rounds before live fire. For convenience, pre-installed options are available.
How often should I clean magazines with extensions?
Clean magazine extensions every 500-1,000 rounds or quarterly, whichever comes first. For competition or duty use, inspect before each training session. Quality extensions with removable floor plates make maintenance simple—access the spring and follower without full disassembly, wipe components clean, and lubricate lightly. Inspect for wear, cracks, or deformation during each cleaning. Extended magazines used for carry should be inspected monthly.
Will magazine extensions void my Glock warranty?
Aftermarket magazine extensions typically do not void Glock pistol warranties, as magazines are considered accessories separate from the firearm. However, always verify with Glock customer service for specific warranty questions. Quality magazine manufacturers like Shield Arms offer their own lifetime warranties independent of Glock's warranty coverage, protecting your investment in magazine components.
Are magazine extensions legal for concealed carry?
Magazine extensions are legal for concealed carry in most U.S. states, but magazine capacity restrictions vary by location. States like California, New York, Colorado, and others have capacity limits (typically 10-15 rounds total). Always verify local and state laws before purchasing or carrying magazines with extensions. Extended magazines may also affect concealment depending on pistol size, holster design, and carry position.
Do magazine extensions work with all Glock models?
Magazine extensions are model-specific. Glock 19 extensions won't fit Glock 17 or Glock 43X magazines due to different magazine body dimensions and base plate designs. Always verify compatibility before purchasing. Quality manufacturers provide detailed compatibility charts listing which extensions work with specific Glock models (G17, G19, G26, G43X, G48, etc.). Some manufacturers offer extensions for multiple models, but each requires its own specific design.
Can I use magazine extensions for self-defense or duty carry?
Yes, quality magazine extensions are suitable for self-defense and duty carry when properly installed and tested. Many law enforcement and military units use extended magazines. However, reliability is critical—only use extensions from reputable manufacturers with lifetime warranties and proven track records. Function test thoroughly (minimum 200 rounds) before relying on extended magazines for defensive purposes. Some agencies have specific approved equipment lists, so verify compatibility with department policies.
Key Takeaways: Choosing Reliable Magazine Extensions
Remember these critical factors when selecting magazine extensions:
- Construction Quality: CNC-machined billet aluminum outlasts alternatives
- Maintenance Design: Removable floor plates save significant maintenance time and reduce wear on components
- Securing Mechanism: Multiple attachment points prevent the 12% separation rate common with single-point designs
- Warranty Coverage: Lifetime warranties indicate manufacturer confidence and protect your investment
- Manufacturing Experience: Choose companies with proven track records in precision manufacturing and quality control
Bottom Line: Magazine extensions are precision mechanical components, not simple accessories. Investing in quality construction and thoughtful engineering ensures reliability when it matters most. The difference between a cheap extension and a quality extension may cost you more than a few dollars saved.
Conclusion
The magazine extension market offers numerous options, but understanding the engineering and manufacturing differences helps identify products that deliver long-term reliability. Whether you're upgrading for competition, training, or personal defense, choosing extensions built with precision manufacturing, accessibility-focused design, and comprehensive warranty backing ensures your investment enhances rather than compromises your firearm's reliability.
Quality magazine extensions transform your Glock's capability—adding 25-50% more capacity while maintaining feeding reliability. But this performance only materializes when extensions are engineered as precision mechanical components, not treated as simple add-ons.

Prefer to read the instructions? Continue with the detailed written guide below.
What You'll Need (Tools and Parts)
Required Tools
- 3/32" punch (or similar small punch)
- Small hammer (plastic or brass preferred)
- Needle-nose pliers
- Gun vise or padded surface for stability
- Safety glasses (metal parts can spring out)
- Good lighting for small component work
Required Parts
- Shield Arms S15 Magazine (Gen 3 recommended)
- Shield Arms Steel Magazine Catch (Standard or Premium)
- Factory Glock 43X/48 (unloaded and verified safe)
Optional but Recommended
- Gun mat or towel to prevent scratches
- Small container for holding removed parts
- Camera or phone to document disassembly steps
Step 1: Safety First - Unload and Verify
Critical Safety Steps:
- Point firearm in safe direction at all times
- Remove magazine from pistol
- Lock slide open and visually inspect chamber
- Insert finger into ejection port to physically verify empty chamber
- Let slide close and dry fire in safe direction (if comfortable doing so)
- Remove any ammunition from work area
Pro Tip: Even experienced shooters should follow these steps every time. Complacency with firearm safety can have tragic consequences.
Step 2: Remove Factory Magazine Catch
Locate the Magazine Catch Components
The magazine catch system consists of three parts:
- Magazine catch button (visible on left side of frame)
- Magazine catch spring (inside frame)
- Magazine catch body (extends through frame to catch magazines)
Disassembly Process
2.1 Position the Pistol
- Place Glock in gun vise or on padded surface
- Ensure muzzle points in safe direction
- Have good lighting on work area
2.2 Compress the Magazine Catch Spring
- Look through magazine well from bottom
- Locate the magazine catch spring (small coil spring)
- Using needle-nose pliers, gently compress the spring upward
- This relieves tension on the magazine catch components
2.3 Remove Magazine Catch Button
- While maintaining spring compression, push magazine catch button from left side
- The button should slide out toward the right side of frame
- Catch the button - it can spring out with force
- Set button aside in small container
2.4 Remove Spring and Catch Body
- Release spring compression and remove spring from frame
- The magazine catch body will now slide out through the magazine well
- Note the orientation of all parts for reassembly
Common Mistake: Rushing this step and losing small parts. Take your time and keep track of component orientation.
Step 3: Install Steel Magazine Catch
Why Steel is Required
The factory plastic magazine catch is designed for Glock's polymer magazines. The S15's steel construction and different geometry require a steel magazine catch for:
- Proper magazine retention
- Reliable magazine release
- Prevention of magazine binding
- Long-term durability
Installation Process
3.1 Prepare Steel Magazine Catch
- Remove steel magazine catch from packaging
- Inspect for shipping damage or defects
- Note that steel catch may have different texture/finish than plastic OEM
3.2 Install Magazine Catch Body
- Insert steel magazine catch body through magazine well
- Ensure proper orientation (catch faces toward trigger guard)
- Body should slide through frame easily without force
3.3 Install Spring
- Position magazine catch spring over catch body
- Spring should sit in designated groove on catch body
- Ensure spring is not twisted or bound
3.4 Install Magazine Catch Button
- Compress spring using needle-nose pliers
- Insert steel magazine catch button from right side of frame
- Button should slide through frame and engage with catch body
- Release spring compression gradually
3.5 Test Magazine Catch Function
- Press magazine catch button - it should move smoothly
- Release button - it should return to flush position
- There should be no binding or sticking
Step 4: Test Magazine Function
Initial Function Check
4.1 Insert Empty S15 Magazine
- Insert S15 magazine into magazine well
- Magazine should slide in smoothly without resistance
- You should hear/feel a distinct "click" when magazine locks in place
- Tug on magazine - it should be securely retained
4.2 Test Magazine Release
- Press magazine catch button firmly
- Magazine should drop free immediately
- If magazine doesn't drop free, see troubleshooting section below
4.3 Repeat Test Multiple Times
- Perform insertion/release cycle 5-10 times
- Ensure consistent, reliable function
- Magazine should lock and release identically each time
OEM Magazine Compatibility Note
Important: After installing steel magazine catch, your factory Glock magazines may:
- Not drop free when button is pressed
- Require manual extraction from magazine well
- Show increased wear on magazine body over time
This is normal and expected. The steel catch is optimized for S15 magazines. We recommend using steel magazines with steel catch and plastic magazines with plastic catch for optimal performance.
Step 5: Load and Test S15 Magazine
Breaking In Your S15 Magazine
5.1 Initial Loading
- Start with 10 rounds for first loading
- Use quality ammunition (avoid steel case for break-in)
- Load rounds slowly - new magazine springs are stiff
- Don't force rounds if resistance is encountered
5.2 Gradual Capacity Increase
- First range session: Load 10-12 rounds
- Second session: Load 13-14 rounds
- Third session: Load full 15 rounds
- This gradual approach helps spring settle properly
5.3 Break-In Period Expectations
- First 100-200 rounds: Magazine may feel stiff
- Loading resistance: Normal for new steel magazines
- Minor feeding hesitation: May occur during break-in
- Performance improvement: Should be noticeable after break-in
Live Fire Testing
Range Testing Protocol:
- Start with 10 rounds loaded in S15 magazine
- Fire slowly - allow magazine to function properly
- Check for feeding issues or malfunctions
- Gradually increase rate of fire as confidence builds
- Test with different ammunition types if desired
What to Expect:
- Reliable feeding
- Consistent ejection patterns
- No increase in malfunctions compared to OEM magazines
- Identical shooting experience with 50% more capacity
Common Installation Mistakes to Avoid
Magazine Catch Installation Errors
Using Wrong Orientation
- Magazine catch body has specific orientation
- Catch must face toward trigger guard
- Reversed installation prevents proper magazine retention
Insufficient Spring Compression
- Spring must be fully compressed during assembly
- Partial compression can cause binding
- Use proper tools - don't force components
Cross-Threading or Binding
- Components should slide together smoothly
- Forcing parts can damage threads or surfaces
- Take apart and restart if resistance is encountered
Testing and Break-In Mistakes
Skipping Empty Magazine Testing
- Always test magazine insertion/release before loading
- Problems are easier to diagnose with empty magazines
- Loaded magazine malfunctions can be dangerous
Loading to Full Capacity Immediately
- New magazines need gradual break-in period
- Loading 15 rounds immediately can cause feeding issues
- Gradual loading schedule prevents problems
Using Poor Quality Ammunition
- Steel case ammunition can cause feeding issues during break-in
- Stick to brass case, quality ammunition for initial testing
- Establish reliable function before trying different ammo types
Troubleshooting Installation Issues
S15 Magazine Won't Insert Properly
Possible Causes:
- Magazine catch installed incorrectly
- Magazine catch spring binding
- Debris in magazine well
Solutions:
- Verify magazine catch orientation - catch should face trigger guard
- Check spring position - ensure spring isn't twisted
- Clean magazine well thoroughly before installation
- Test with OEM magazine to verify catch function
Magazine Won't Drop Free
Most Common Cause: Wrong magazine catch installed
- Verify steel catch installation - plastic catch won't work reliably
- Check catch button travel - should move full distance
- Inspect magazine catch engagement - should be clean release
Other Possible Causes:
- Debris in magazine well
- Magazine catch spring binding
- Frame tolerance issues (rare)
Solutions:
- Clean all components thoroughly
- Verify proper part installation
- Contact Shield Arms customer service if problems persist
Magazine Binding or Sticking
Typical Causes:
- New magazine tightness - normal break-in issue
- Inadequate lubrication - rare but possible
- Frame dimension variations - uncommon but possible
Solutions:
- Continue break-in process - most binding resolves with use
- Light lubrication of magazine body sides (sparingly)
- Professional inspection if binding persists after break-in
