You may already know this but just in case you don't... "The Peacemaker" or just "Peacemaker" is a real-life nickname for a Colt Single Action Army pistol (which is what the Character Wynonna Earp uses, though with a longer barrel than normal), meaning one shouldn't call any other pistol a Peacemaker. The pistol you are using as a base for your prop is nothing like a Colt Single Action Army.
