Best?
Best revolver would be my friend Randy's... Smith & Wesson? (haven't been into revolvers at all; just finally ran across a Colt that was at a right price) Had about a 4" barrel, and shot .357... with a trigger pull that must have measured in ounces.
Neat gun.
Best semi? I shot a 1911 type Kimber in a class; liked it a lot, but my fave would have to be my little .22 Ruger Std. When I brought her home as a newbie, she was so full of lead and powder residue that I couldn't believe she was ever gonna' shoot worth a darn.
After an hour of cleaning (literally, about a half teaspoon of shmutz came out of the reciever, bolt, and other nooks and crannies), and another hour figuring out how to get a Ruger Standard back together (hint: Google searchstring should include "youtube", "dingle" and "cheese"), I got her ready for the range.
7 yards, first one down the pipe went through the black part of the target... KEEPER!
I've since then honed that sear mechanism and fiddled with springs; very light trigger. Just recently added one of those extended mag releases, too.
The grips' checkering is worn halfway off, I finished off the original magazine and extractor claw (had to replace 'em after several bricks - on top of whatever she'd had before) and the finish is really tired - but it's my favorite, over my G21, FEG PA-63, FN 1906, Browning Hi Power, or my Detective Special.
I'm not an awesome shot, but on a good day, I can put a magazine of ammo all on a pie plate from as far as I can run a target out at Sam's (70 or 75 feet). Which is better than I ever do with anything else.
