Well, I went out and bought a Kimber mag yesterday. I'm impatient :spankme:. I'm going to check out the McCormicks, thanks Janq for the link.
The Kimber fits my gun alright, I'll shoot with it this weekend. It doesn't fall freely out of the gun, though. But neither did my stock mags until I oiled them and used them a bit. Pics aren't too good due to my phone camera, but you'll notice the only difference is the follower is shaped a little differently and the Kimber has a flat bottom, whereas the Taurus has a pad.
