its a colt 1911 probably. it was fairly common for these to see service and then make its way back home. if i'm not mistaken the dcm released some 1911's to members of shooting teams back in the 80's so it could have come from there. i'm due a firearm but its a once in a life time deal for competition shooters. not sure of all the ins and outs. i could have and qualify for a M1 Garrand for like 112 bucks. maybe i should look into that. good luck on finding the history
