S15 9MM LUGER MAGAZINE FOR GLOCK 43X/48 GEN3 Reviews & Ratings

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.

Shield Arms made the following improvements with their Gen 3 Magazine:

New US-based manufacturer
Modular tooling, allowing us to make the S15 and S10 magazines simultaneously
Raised ribs on the back of the magazine allows us to fully match the OEM magazine position in the mag well, which should eliminate any tolerance stacking that results from Glock frame variations
New steel, new coating, new heat treat process - The new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance.

Mag Catch Requirement: It is required to swap out your plastic OEM mag catch with either the standard steel mag catch or the premium steel mag catch. Here's why. If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues. S15 magazines were designed to work with Shield Arms steel mag catches.

STANDARD FEATURES

15 round capacity - Increased Capacity, Same Reliability
Same length as an OEM Glock 43X/48 magazine
Easy to remove, impact resistant base pad
High lubricity finish options
Made in the USA, Patent-pending

ADDITIONAL FEATURES OF MAGAZINES WITH PRE-INSTALLED +2 AND +5 EXTENSIONS

Shield Arms S15 Gen 3 PowerCron 15 round 9mm magazine with an anodized Shield Arms +2 and +5 magazine extensions pre-installed. The unique, easy access floor plate design allows you to quickly access the spring and follower without having to remove the extension from the magazine body. Comes with a 100% lifetime warranty, and the Shield Arms Spring for Life guarantee.

Great Mag's

These mags work great out of my glock 43x. Just be sure to upgrade with the new mag release or it will chew the polymer mag release up. I still use my factory 10-round mags but I push the mag release and insert the mag and then when I remove the mag I hold the magazine in place and hit the release that way it does not do any damage to my factory mags which I use sometimes for target practice instead of using my 15 round mags

Would you recommend this? Yes, I would recommend to a friend

S15 Mags

Great Mag but buy it some where else for a much better price...Go right to Shield Arms, MagShack, and Primary Arms all have this same exact item for a much better price! I'm just saying...

Great magazines

Awesome magazines. Glad I ran up on these. Have shot many rounds with them, so far no jams or misfires. Would have liked to seen them a little cheaper though, but who doesn’t

Great product

Love these mags. I run them exclusively in my 43x. Had a few issues with the original gen1 mags, but have not had a single issue with the gen3 mags.

Great upgrade over factory Glock mags

I have several gen 2 and gen 3 magazines. Some with extensions and some without. All are a great upgrade from the Glock factory 10 rd magazines. Alows you to carry slim line glock 43x or 48 with minimum of 15 rds. I carry a spare mag and keep 1 in car as well. Function well with their magazine releases. Don’t use with plastic glock oem mag release.

What’s not to like!

I bought my Glock 43x because of these magazines. 16 rounds in a compact 9mm should go a long way in helping you get out of a bad situation. It’s been my EDC for about 18 months. I’m a retired LEO and can carry in most of the places I frequent. I have a couple of pancake holsters, kydex and leather which hold this pistol close and comfortably. I have never had any malfunctions while using these magazines.
