I was informed that there is available a S&W model M&P in 32-20 at a local shop. This revolver supposedly has a 6" octagon barrel. The asking price is $375. Now while I don't really need another revolver, I am a fan of the 32-20 and would like to know if indeed S&W did make such a revolver with a 6" octagon barrel in this caliber. Could this have been a 'custom' order? The grips have been replaced and it may have been re-blued also, both of which detract from the value. Those are secondary right now, the primary being, was this revolver made as-is or was the barrel replaced at one time too?
Any information would be appreciated.
