Hello everyone, i desperately need your help! Ok, i just picked up my springfield armory 1911 GI .45. The problem is that when i fire a round, about 2 out of 7 times the shell will fail to fully eject and gets caught in the slide. Im pretty sure thats stovepiping? Do i need to just break it in or what i only fired 150 rounds so far, but shouldnt it work fine out of the box? I tried 5 different mags, as well as 2 brands of ammunition and 3 different shooters. All the same problems. If anyone can help i would immencely appreciate it. Thank you in advance.
