Shield Arms S15 Magazine For G34X and G48

When the G43X and G48 were introduced a lot of users thought the size of the grip's girth was just right. Those with smaller hands liked the single stack magazine and thinner grip. But with the new grip came some gripes. (Some people you just can't please.) It's only a 10-round capacity magazine. Long story short is GLOCK wanted to provide pistols to shooters in states were a 10-round magazine is mandated. Plus these pistol met Canadian pistol laws.

So to satisfy the More-Is-Better shooter, Shield Arms introduced a 15-round magazine for the G43X and G48 and there is not a magazine extension sticking out of the grip. This is a flush fit magazine.

The big difference, other than the capacity, is the Shield magazine is made of steel. Using steel allowed Shield engineers to create a magazine body that is thinner and  allowing the extra 5 rounds.

Shield recommends swapping out the plastic OEM mag catch with a metal magazine catch:

"Steel being harder than plastic, eventually using S15 mags with a plastic catch will cause feeding problems. How long this will take depends on a bunch of different factors, most importantly, your specific gun and how much you shoot. We have guns with plastic catches with many hundreds of rounds that are still functional, but some customers report excessive wear after just a couple hundred rounds. Feeding issues also seem to occur much faster in early gen 1 (silver slide) guns with plastic catches vs. gen 2 (black slide) guns because of the differences in the frames."
