No favorite brand, overall. Several are good for me, in various ways. My favorite individual revolver is the GP100 that I used one night in the gravest extreme, in a contest with no second place winner.
The words "in the gravest extreme" borrowed from Mas Ayoob, the title of his excellent book.
The words "no second place winner" borrowed from the title of the excellent book by the late, great Bill Jordan.
I cannot imagine life without my Ruger, Colt, S&W, and USFA revolvers, with models from each maker filling niches. The factory grips (pre-Hogue) on the GP100 and SP101 are perfection for my hands. An S&W Model 19 is, well, it's own class of fightin' sixgun that is eminently packable while being just as shootable as anything on the planet, with an equivalent barrel length. USFA makes excellent sixguns, and SCARED Colt into making great sixguns again. Colt, because they made the first widely successful revolving pistol, culminating in the SAA.
