I am looking into getting a colt for competition. there are a few i could possibly get, but what series should i look for? i'd like to modify it so take that into consideration. the guns are a few years old, but are in mint condition, sitting in my grandfather's safe. They are probably model 70s and i remember seeing mk iv on one of them. just throw out some ideas and thoughts for me. thanks
Also, i think i remember one saying Double Eagle on it.
