Okay old farts and gun guys. Looking for some advice and feedback. I'm considering buying a Model 64. J&G Sales has several flavors of old ("new" or "recent" if you're named after a blackpowder pistol and have someone's bust size in your screen name) police trade-ins in stock: http://www.jgsales.com/index.php/smith-wesson/revolver/cPath/16_211_431 Someone tell me about the relative utility of square vs round butt and any pluses to the NY1 flavor? TIA Wanna kill these ads? We can help!
