A friend of mine has offered to sell me his colt combat commander, #70-BS 98xx- he got it from a friend of his and carried it on PD for years, he no longer shoots. the friend he got it from bought it new from Colt, but it is not the same as other colt cc I have seen, it has adj. sights, and a spur hammer. he said it was that way when he got it? can you tell me any thing about it? I don't have a picture ; only one mag. no box or papers. did colt offer options like that from the factory? approx. value? it;s not beat up, just holster wear,I would say it's 80-85 percent. can you tell me the year it was made?
