DA Revolers-
Square-butt K and N frame Smiths with Magna stocks feel good to me, along with the Redhawk with its factory wood grips.
SA's-
The 1860 Colt hands down, followed by a 4 3/4" Colt SAA or direct copy. I can get along with the New Model Rugers (large frame) adorned with hard checkered grips. Ruger Bisleys are OK, too.
Autos-
1911's & CZ75's fit me; I've 'fit myself' to the Glocks as a matter of survival. I get along best with the 3rd generation G22's and 2nd generation G23 grips, but I shot a G21SF the other day and they've pared that one down nicely. I actually did decent work with it at 25 yards from a bullseye stance, so something must have been right.
Us guys with 35+ years on handguns have seen a menagerie of designs pass by. I soon learned that the ratio of adaptation, for lack of a better term, is about 85/15 for shooter to gun.
Pick a gun that meets your needs, fits you pretty well and can be easily modified to clean up that last 15 percent. Then live with it, master it and ignore everything you see in gun magazines until you've actually shot something that does it better. The gun and accessory hawkers won't like you much but I seem to be able to sleep well, all the same.
