I've gone on a bright nickel rampage lately. So far I have added a 1975 Government, a 1981 Python with a 4 inch barrel, and a 1972 S&W model 19-3 snubbie (had to put mother of pearl grips for the total pimp look). Anyway, I think I need to add a Combat Commander. Are they rare? I haven't seen one at the gun shows (not in Dallas anyway). What should I pay for a 98% condition specimen? Thanks in advance.
