Hello all, New to the forum but I have recently encountered a problem and I can not quite figure out the cause. Bought the Glock 48 the moment I saw it, loved it from the get go. As most might have, I bought the shield arms S15 15-round magazine and aluminum mag catch. I replaced the factory mag catch release with the metal one as recommended by shield (a lot more difficult than I thought.) I eventually got it and things were great, my new carry gun was slimmer than my 19 and held the same amount of ammo (15) While training the other day I noticed the new mags (S15) came out after firing. After trying to guess what it was I could not diagnose the problem. Beyond frustrated I took my gun apart and noticed that the aluminum mag catch provided by shield was rounded/worn already. I had less than 200 rounds through these mags. Has anyone else encounter this with their 43X/48? I switched to a factory mag and they seemed to work fine.
