May I suggest that you focus your efforts on the SIG P220 series. While I enjoy shooting a top-quality 1911 pistol, the SIG seems to be kilometers ahead in terms of function, fit, finish, style, ease of use, etc. And the bloody SIGS just work!
I used to own a P220. It was a nice gun, but it never fit my hand very well. It also was larger than a Lwt. Commander which I had at the time, so I decided to sell the SIG. I might also mention the SIG was a bit fussy about some brands of ammo, most notably CCI 230 grain FMJ Blazers. Both it and my Series 80 Government didn't always like to feed them reliably.
Of course, with the 1911 it was naturally the fault of the gun, but with the SIG it was the fault of the ammo. Right?
