I just bought a used Colt MK IV series 80 "Officers" model in .45 ACP .
It's all nickel and for a 25 year old gun is in great shape.
It has wooden grips and someone added a ambi safety (which I need) to it.
We took it completely apart in the store & wiped it down (it was already cleaned) and lubed the slide & rails.
I bought it for $510.
It only has one mag & no box or papers.
I can't wait to shoot it this weekend.
