I earned my Triple Nickel with my issue P229 in .357SIG. I've also passed the criteria with a G19 and a Beretta 92G. Same for my 2 John Harrison-built 1911's; a 5" SAI TRP and a 4" STI Ranger II. For me, I can pass the Triple Nickel much more often, with significantly faster times, with my 1911's than I can with my SIG or G19. Nope that ain't part of the criteria for a carry or duty gun, but I run a 1911 better than I run anything.
