I am with Pilot.....
A nicely tuned Government model..........take your pick as to maker and 'smith. The other various models of the 1911..Commander, etc are in the bunch too. But the classic Gov't in battle trim is the one to beat.
Prettiest....the Clark Damascus Meltdown. Followed by some tastefully engraved models.
Must give an honorable mention to the Sig P220 though...been around for decades, graceful, nice trigger, reliable, and accurate.....
Ahh, the UMP, though not a pistol...it is where .45 cal subguns needed to go.....accurate, light, reliable thump!
The other's are interesting, and useful, if ya want 'em, get 'em. As long as they are reliable, .45's and you can hit with it.......then it is a GREAT defensive and general purpose tool!
