The S15 magazine is a patent-pending, flush-fitting 15 round magazine for the Glock® 43X and Glock® 48. The S15 is a steel magazine, and is the same length as the OEM Glock® 10 round magazine, but holds an additional 5 rounds.

Increased Capacity, Same Reliability

Glock® pistols and magazines are known for reliability - the S15 maintains that same Glock® reliability, while giving you a 50% increase in magazine capacity in the same overall footprint.

We accomplished this increased capacity with our patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.

The S15 is currently only setup for right handed mag catch (left side of pistol). We are currently working on an ambi version, release TBD.

Proudly made in the USA by Check-Mate.

Mag Catch Recommendation

We recommend swapping out your plastic OEM mag catch with a metal mag catch. Here's why.

Specifications

  • 15 round capacity
  • Same length as an OEM Glock 43X/48 magazine
  • Easy to remove, impact resistant base pad
  • High visibility follower
  • High lubricity finish, Black Oxide coating
  • Made in the USA
  • Patent-pending

Finish Options

S15 magazines currently come standard with a Black Oxide coating. Black Oxide offers only minimal corrosion resistance, so we recommend that you wipe down the exterior of the magazine with WD40 or your favorite gun lubricant to prevent corrosion.

Electroless Nickel

Electroless nickel coatings are extremely uniform, corrosion and erosion resistant and provide excellent lubricity. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.

See S15 in Electroless Nickel finish here.

Black Electroless Nickel

Black electroless nickel plating combines the same exceptional deposit properties of traditional electroless nickel plating but with conductive, black surface finish. It combines the exceptional lubricity, deposit uniformity, hardness and corrosion resistance of electroless nickel with a fully conductive and uniform black appearance. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.

See S15 in Black Electroless Nickel finish here.

Warranty

Like all Shield Arms products, our S15 magazine comes with our 100% lifetime warranty against manufacturing defects. Additionally, we also offer a Spring for Life Guarantee - wear out your spring, get a new one for free, for life.

15 round magazine for the Glock® 43X/48
Hi!

I just bought a Glock 48 today only because you're coming out with a 15 round mag. I can't believe you guys made it happen, amazing.

I signed up for your newsletter. Any word when they will be available? No worries if not, I'm just super excited.

Wanted to leave you a positive review just because what your doing for our industry. Thanks guys for leading the way with innovation.

Really pulling for this...
Like Kevin, I too made the final decision to buy a 43x based on your potential release of this magazine. The gun is great overall, but having a 15rnd mag would make this the perfect marriage of the 19 and the 43. I truly can't wait to see this new mag. I also signed up for the newsletter and anxiously await the good news.

15 round please!
I carry the 43X daily as my duty firearm (plain clothes) and carry several 10 round mags for additional ammo. I can’t wait for this to come to reality. I want 3 of these to compliment a full duty load with minimal weight and imprinting. Waiting to drop some cash on you guys!

Well made, reliable
I love this mag for my glock 48 which is my primary conceal carry weapon.  The only negative aspect to this mag is, it’s only cut on the one side for a right handed mag release.  No love for the left handed shooter.  I wish it would have said that in the description!

15 round mag. 43x
I ordered 2 of these magazines to test out on the range. I ran them heavy and empty at full capacity and had no issues what so ever. I am extremely happy and ended up ordering 8 more for me and some people I work with. Keep up the good work!

Amazing innovation
I am so impressed with the magazines. I got the mags today and ran to the range and put 200 rounds through without any issues at all. This was the best idea ever to have metal mags and to hold 15 rounds. It makes my 43X 10 times more useful and valuable as a conceal and carry or in my vehicle for emergency use. Thanks for making my 43X even better now.

The S-15 saved the Glock 43x!
The S-15 magazine is a must have for anyone using a Glock 43x/48. This mag is tough, reliable and classy in the new electroless nickel silver finish. Most importantly the G43x/48 now has a capacity of 15 1 (20 1 if you get the  5 mag extension). GET THIS MAG!

Love the magazine, only one issue
Magazines work great, I have 3 S15 and 2 of them have the 5  extension. Carrying 55 1, run great and no jams or failure to feed. Only issue I have is the rounds rattle inside of the magazine, a big issue for me but all mechanically speaking is perfect.

Works just fine
Just received today and put 200 rounds through it. Not one malfunction. Works just fine... Now I hope Shield Arms does the same with the 19 and 17. Imagine your 19 with a 20 round or so flush magazine. GOOD JOB SHIELD!!!

Very Satisfied!
I have 4 of the S15 mags for my Glock 43x along with the aluminum mag catch. I have 500  rounds through them without any failures. This has become my new CCW/home defense weapon and these mags allow me to have excellent capacity. Customer service is excellent as well as I had an issue with one of the mags not having as much spring pressure, emailed the company and within a week had 2 brand new springs in my mailbox. Not everyday you get what you pay for with good customer service. Would highly recommend.
