I have a 1911 springfield champion model. Yesterday I went shooting with this and my new to me glock gen 3 19. The glock had no issues,except that I could not hit squat. Im to use to my 1911 which I do pretty good with. Anyway I just bought 2 new chip mccormick power mags that I used with the 1911 and sometimes on the last round slow fire only that last round would hang up in the barrel half way with the slide half locked up. If I fire fast thru the whole mag it did not do it. Using blazer brass and golden sabre ammo did the same. The factory mags never did that. Could the springs be to weak in the chip mags ? That what it seems like. The bullet did not have enough force on it to push it into the barrel and left it half way in and out. Any thoughts. Wanna kill these ads? We can help!
