Shield Arms S15 Gen3 Magazine for Glock 43X / 48 - 15 Rounds - Black Nitrocarb

These mags work perfectly. I have magazines from just about every company but these are the best.

TBH, reading other reviews I was very worried I'd get these and have all sorts of issues. So far, my fears have proven unfounded.

Previous generations seem to be the ones people complain about. Interestingly, one issue seen with previous gens (mag inserting canted towards the rear, then snapping forward once past the mag catch) still occurs with the three Gen3's I purchased, but it seems to have zero effect on function. Remove the slide, insert a loaded mag, and you'll see it. That movement/effect is almost non-existent with the OEM magazine.

Only put 45 rounds through each, but with three magazines, if there are issues, I would hopefully see them by now. Still want to put 100+ rounds through each before I fully trust them, but so far so good.

This in a G48 MOS (stock other than metal mag release, no optic). All 115gr reloads but one mag of randomly mixed reloads and Hornady +p critical duty.

Extends your ammo capacity by 50%. No issues with misfeeds or other malfunctions.I don’t know why I waited so long to buy mine.

Mag was great. Functions with all ammo types, fmj, flat tip, and multiple jhp from 115 to 147 gr. Locked back on empty. Only drawback is need metal mag release. I put a Glockstore extended in works great.

Great product, adds 50% capacity to magazine. Visual count on side of magazine helpful.
** These only worked for me when using Shield Arms Steel Mag Catch ** but that was easy to install.

Magazine works flawlessly, would suggest purchasing the kit. And Five Stars to Primary Arms !!!! Always a great experience from website ordering to delivery. Thank You !!

Work’s as it should,reliable

Purchased the Shield 15 round magazines for my 43x and still trying to figure out how they got 5 more rounds in the same space as the 10 rounds magazine. Feeds and ejects as well or better than the Glock mags. Great product.

I bought Gen 1 mags before I bought my first 43x. It took months to get them and when I got them I went and bought a G43x with the Trijicon day/night sights. I left the 10 round Glock mags in the box and stashed it with all my other boxes from gun purchases. That combo worked so well I bought a G43x MOS and have only used Shield arms mags with it as well. I acquired a bunch of Gen2 and Gen 3 mags now and have had no issues at all. I’d be skeptical about these mags now considering there are people claiming they have problems with them but I got on this band wagon before there were reviews and have had none. I like these mags and have so many I just added an Alpha Foxtrot S15 double stack 1911 to my collection that also uses these mags and it’s been great too. At $30 each this is a steal. If you buy them, please leave a review as I’d like to know how others feel about them.

I carry 14 in mag and 1 chambered (that 15th round is tight). Amazing solution to thick walled G mags to get great capacity for EDC use.
