On a couple threads you may have noticed im trying to select another revolver. My revolver experience is limited at best. I have found some very nice 3" barrel guns. Normally I consider anything 4" or less a carry weapon. I live in NJ so I will never use it for that, besides I already own a PA63 which would make a great pocket gun. So why choose short barreled revolvers if not for carry? Am I able to take advantage of a 357 power in a 3" barrel? If not at what length barrel does it start to become a "magnum"?
