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.
