I like your Original Colt but don't care for the 'safety' non original styled models...this is my snaker/varmint Colt....is very accurate as the rear and front sight in the '71 model are on the barrel.
It has the same hammer / sear system as the later Colts.
This was the modern Colt design made from the pre cartridge/cap and ball models before the '72/'73 popular Colt single action we all grew up with.
