Kind of a toss-up between my 4-inch 686+ and, strangely enough, my Kimber UCII. The three-inch barrel may affect the speed the bullet is traveling downrange, but I can make headshots every time at 15 yards with no trouble, and at 25 almost every time ... amazes me every time it happens. I'm seriously rethinking my carry guns and although pocket carry is almost mandatory here in the summer because of the heat, I'm looking for way to tote that little 1911 year-round ...
