Guys, just got my norinco 1911 from the gunsmith. I tried dry firing dummy bullets and i noticed that when i use the CMC mags on it the slide will not remain open when the last round of the dummy bullet is ejected. Is it the mag catch or the magazine. Also, the magazines are hard to insert and I have to push it hard before the mag catch clicks to its locked position. Wanna kill these ads? We can help!
