Smith & Wesson model 1902 M&P

It's funny with the little 1" barrel, I can't Imagine it being accurate at all. Seems so puny to have been carried by a cop.
Yeah, those are tough to get accurate with. Was your dad eventually a Cheif or someone high up in the dept? I've heard the high ranking guys carried the snub nose guns. I know s&w started calling the snub J frame a 'cheif's special' in the early 50s!
