Most of the early mountain men and traders carried a single-barreled pistol and they were popular for years. These pistols had proven themselves reliable, and that was of great importance to a trapper who might have to stake his life on a pistol's ability to provide a back-up shot in what could be a desperate situation. The Trapper pistol's primitive-style adjustable rear sight, octagonal barrel and doubleset triggers (capable of firing set or unset) allow you to predictably put your shots on target. This particular pistol is 50 caliber flintlock and has a 9.75" octagonal blued barrel. It is 15.5" in length and has a select hardwood stock.
