I am considering buy a single shot revolver with bird's head grips because I really like the look. The caliber will be 357 in a 3" or 4" barrel. My only concern are the grips. Can anyone here let me know if the grips are comfortable enough for big hands? I'm 5'10 280lbs. My 2nd choice is a S&W 686 in 3" barrel, I already own one with a 6" barrel
