Oh sure...a lot of gun dealers have the lore...but check this out..I worked as a gunsmith at Detonics` both in manf., and in the custom and repair dept...the frames came in with the serial numbers already in them..for a short period, we were allowed to order them with special serial #'s, even initials. I built one up back then, the serial # was CR-JAM, a cut-down version before the mk VII project..This is the first time I have seen this site, but some of the advice/info/data/legends are not quite correct..
