Sometime I do not have a round in the pipe and sometimes I do, for various reasons...when I put a round back in the pipe, I lock the slide back and insert a round, then close the slide, that way I don't have to replace a round in the mag, in my 1911's this works fine, but in my PT145 Mil Pro(3rd Gen), when I do this the slide will Not go All the way forward, and I don't want to force feed it, anybody know what is goin on here...Thanks!
