Colt Combat Commader/Para Ordinance
I have a Colt Combat Commander 45 ACP with a Para Ordinance lower unit (grip, trigger etc) 13+1 serial # PK00xxxx. I also have the original Colt lower unit (grip, trigger, etc) serial # 70BSxxxxx. It had been in a safe since the late80's, was removed to install Para Ordinance unit in the early 90's, put back, and shows minimal wear. Any ideas as to approx value?
