First of all let me say I love this forum and the wealth of knowledge here. Here's the problem I am having I had a 9mm upper built for my edge to shoot in the Pro-Am. So I ordered complete 9mm sv mags to use. The gun runs flawless with all the mags except for occasionally they all lock the slide back with one round still in the mag. I've checked to make sure that its not the bullet nose hitting the slide stop causing my headache. Normally this isn't and issue BC in limited form my gun has the slide stop disabled but for the Pro-Am I want the slide stop to work BC of the 10rd limit. Thanks for any and all help.
