I just bought Scoremaster #CRM 3XXX. Nice gun, have not shot it yet though. This has a 5" bbl and Pachmayr grips including a small piece below the grip safety. It is stamped "Bellevue WA". What sort of value do these have in todays market? Is there any glitch a guy has to watch for? If I wanted to put a grip mounted aim point on this are the grips same as a 1911? Thanks and great site!
