Actually it was earlier than that, I bought mine in 1980, with production starting in 78 or 79. The satin nickle finish is called "Colt Guard" it is nothing more than electroless nickle. There was no special name for these and they did not have special serial numbers.Originally posted by webley 455:
That was arun of Gov't. Models made up by Colt around 1983 or 84. No special model number or name was assigned.
