So I just got my Metro Arms 1911 American Classic II government model and I'm having a small feeding issue. Its got a factory 8rd mag (ACT-MAG I think). It has no issue with ball ammo ever. If I load the mag totally full with hollow point rounds and try to chamber the first round in it jams almost every time. But this ONLY happens when I'm chambering the FIRST round from a FULL mag and the chamber is CLOSED when I load the mag. If the mag only has 7rds loaded or if I insert the full mag with the slide fully open and then chamber a round it works fine. The guns already thoated and polished so I'm thinking its a mag problem . What do y'all think? What do I do to fix it?
