So I'm fairly new to shooting. Got my first gun in August (CZ75B) and have quickly followed with 5 more. Long story short, I joined a pistol team and bought a MK ll from a member. Great gun, far more accurate than me. But, it seems when I load a full mag (not sure if it's 1 mag or both, I guess I should really check it) it seems to jam on the 2nd and 3rd rounds. It nearly bends the bullets in half. I have not noticed this when I only load 5, only 10. I may see the guy I bought from on Sat. and ask him, but between then, what say you? New mag springs? If so, where?
