|I've heard a lot of good about CMC mags online, but never found a gun shop that carried them on the shelf. Now I know why.
These have the worst followers I have ever seen.
First, they don't lock the slide back, just slip past and hang above the slide stop, making them hang in the gun.
Second, they rock forward after the last round and hang on the ramp, adding to the problem of hanging in the gun, aside from the damage they could do to an alloy ramp.|
