Last year, my father gave me his 1981 production Ruger Standard Model. She has a 4 3/4 inch barrel and good quality fixed sights. Her trigger is quite nice, breaking at about 2 3/4 pounds, but having a decent amount of creep.
I make no claims about being a handgun shot, but from a rest at 10 yards this pistol will put a mag full of CCI standard velocity long rifles into an inch. At 25 yards she's right about 2 inches. Of course offhand is much larger. I'm thinking of a Volquartsen trigger with pre and overtravel adjustment. Granted I'm newish to handguns and I expect that I'll do better with more practice, but I'm wondering what to expect of this fine pistol in terms of accuracy.
