On the plus side, if you do get a bad promag, you can get plenty of malfunction drills in.
I'm 0-3 on Promags. They won't get a chance to go 0-4.
Stick to to fsctory mags. What size mag you looking for? Might sell 1 or 2 of mine.
After the lashing that Promag got here, I think ill stay away from them. .45 6 round mid mag is what im looking to get more of.
I have had some varieties of Promags which have worked well but for the most part they are well inferior to factory mags. I have an M&P9 promag I use at the range but would never carry it.
