I own 10 tapco mags. Not a single complaint out of any of them. I got some from the shop I was working at for $6 at that time and each one has personally seen over 200 rounds each since I've owned them. I'm pretty hard on them too as far as speed reloads and having them hit the dirt, concrete and gravel. Tapco doesn't usually have top notch products but their trigger groups and mags are impressive for the money.
