After trying other mags I've settled with the Wislon's 47D series. I just dont see any need for another mag. My number of malfunctions since switching to the Wilson mags has been exactly Zero. I've got at least 5K rounds through my Springfield M1911 using these mags. I paid $20 each for my last 5, how much are these wolfe mags going for? For serious use stick with Wilson's, they're proven mags.
