Today I put a used Colt MK IV Series 80 on layaway. Its the blued Government model that is bone stock as far as I could tell. About the only think wrong with it was a minor scratch on the frame, but thats no prob cause its going to be a build up. The gun seems like it was never fired or the owner just took real good care of it. Total w/ tax and everything came out to be $520 and I am wondering if I got ripped off or is it a steal? Also, what do you guys think about using this as a base gun or should I continue to look for a Series 70?
