I am just getting started collecting, and dont have any books yet, so maybe someone here could give me some info on my gun. It is a Colt officers model 38 heavy barrel. The ser.# is 6503xx. Besides the date of mfg.,I need to know what kind of grips would have came on this gun, so I can begin my search for a set. The gun is real nice, but the grips are gone. Thanks for your help.
