I finally found my gemstone, diamond, dream gun. A smith and wesson 629 4 inch revolver in .44 magnum. I have been wanting a 29 or 629 since I saw dirty harry. Is 700 dollars a good price for one of these slightly used. Is there a difference in an older one and a newer one? My gun guy said something about having three lugs or something like that, anyone know what he was actually saying?
