Flat nose tmj 380 ammo inc failed - Ammo, Inc. .380 Auto 100 Grain Total Metal Case Brass Cased Centerfire Pistol Ammunition

Please don't use these in a Glock 42.except for Hornady critical defense or seer gold hp. After the first Glock that requires breaking, about 300 rds or so as well as the magazines.My Glock 42 is now as reliable as a Glock
Should. Stick to round nose fmj as I have shot flawless cycling for at least 1000 rounds. Those flat nose would not go 2 rds with out ftf,fte jamming in ways I don't think I ever saw. My Glock 48 mos right out of the box has never failed using anything fmj,hp.flat nose. At around 2000 rds with it.Just stay with round nose In you 380 acp Glock 42 and I have 2 of the best defense and great range day guns as these are accurate and just fun as heck to shoot¡!!!!!!
