I picked this up at the LGS because it looked like an early S&W mag. However, its style is pre-3rd gen (by the baseplate), but it fits my 3913 fine. It has only 7 round capacity.
What was it made for? I've never seen a 3rd gen with a steel base plate, and the only 7 rounders I've seen are the short ones for the early 3913TSW models with the cut-out frame (and this is not one of these short mags, since it fits my 3913).
So, what is it for? Also, how the heck do you get the base plate off?!?
