Used to own a SA GI Loaded, and before that a Kimber TLE II, pre-rail.

On my Sigs and my M&P. I could neglect changing the recoil spring for an extra 5K rounds, or never change a mainspring at all, and the pistol would work just fine. Not so with the 1911.

For defensive purposes, I want a pistol that I don't need to think too hard about.
