People seem to be having good luck with the 15 round PSA mags for the G43x and G48. Glock is not the end all, be all for knowing what works. Virtually every other manufacturer that makes a micro/compact slim 9 has better capacity and no problems with "making it work." The fact that the P365, the Hellcat, the Canik MC9, the FN Reflex, the Shield Plus all fit in a pocket and hold the same or more rounds than the G43x or G48 with their full size (albeit slim) dimensions shows how deficient the platform really is in comparison.This isn’t anything against you just your statement is an example. The Glock 48 and 43x is exactly what Glock designed. It’s that people never being happy trying to stuff more rounds in than intended was/is the problem. Shield and everyone else found out if reliable 15 round mags made like Glock makes mags wild work Glock would have done it.
That's because handguns suck at stopping people, so it's reasonable to want a higher capacity regardless of platform. I'm not leaving the house with a 5" tall pistol that only holds 10 rounds when I can have the same size (and better grip angle, to boot) with 14 or 15 rounds on board. And the same +50% force multiplier in a spare mag.I’ll say this again people get way to fixated on mag capacity especially in small guns.
