Civil War “Dirty Harry” Horse Pistol Massive 15″ Barrel .50 Caliber Amazing Historical artifact. A very large working 15″ barrel horse pistol circa 1850’s. Most likely made for use on horse back as a kind of stock-less carbine. This is the largest Civil War period pistol we ever had and is defiantly an oddity. We placed a Philadelphia Derringer in one of the photos for size reference (the derringer is not included) this offer is for the large pistol only. It is heavy and massive! There are no maker marks or stamps. It has an excellent working cap and ball system with very tight lock. Both half cock and full cock work well. .50 caliber rifled barrel. Original wooden ramrod is included. Both Confederate and Union soldiers during the Civil War used horse pistols. Many Civil War soldiers carried private purchase “back up” weapons as illustrated in the photo above. This gun is 100% guaranteed to be authentic, and unaltered as found. Complete museum documentation (COA) provided. This is a pre-1898 antique gun so no federal registration is required. This is a working gun but we do not recommend firing antique guns.
