Kirst Konverter for Pietta 1851/1861 with Loading Gate 38 Special for .375" Barrels

Cylinder has a .375" diameter throat for .375" groove barrels. Kirst Cartridge Konverter with loading gate to convert the 36 caliber Pietta 1861 and 1851 Colt Navy revolvers to shoot 38 Long Colt or our 38 special ammunition. This has been done because it is more convenient to load and unload cartridges without having to remove the barrel to access the cylinder. This does make it necessary that you, the owner, cut a loading groove in the right side recoil shield of your revolver and install the loading gate. This is not a difficult task with a few common tools. Simple, step-by-step instructions and a loading port template are included. This is now manufactured with a color case hardened Konverter Ring and gate. All Kirst Cartridge Konverters are precision CNC machined in the USA from 4140 Steel and heat-treated. No F.F.L. required, S.A.S.S. legal and lifetime manufacturer warranty. The cylinders are rated "For Black Powder or equivalent loads only," which includeds the current Cowboy Loads on the market. .45 caliber cylinders must never be installed in a .36 caliber revolver. The Kirst Cartridge Konverter must NEVER be used in Brass Frame Revolvers. Not for original antique Colt Revolver. Complete your revolver conversion process by adding an ejector assembly.

If the groove diameter of your percussion revolver still has the factory .375" groove diameter then you MUST use ammunition that uses hollow base bullets.
