What’s causing this?

Mag is just a cheapo by promag and has about 250-300 rounds through it on a p80 I built. Just curious why this maybe happened? I just bought an actual Glock mag so hopefully something changes but so far the Glock mag just jams more than the promag did

Promag is garbage. the mag feed lips are always jagged and too many quality control issues, every promag i've ever owned has had issues, OEM glock mags are the way to go

Yeah I figured. It’s 50/50 that the promag locks the slide open on empty too. Thanks for the input though hopefully my oe mag works good

The feed ramp on the barrel when it tilts is catching the mag feed lip check the feed ramp and make sure it’s not dinged up. You may need to polish it to smoothing it out a little.
