Product Overview


  • Converts 36 caliber to shoot 38 Colt (Long Colt) "Cowboy" ammunition
  • Will shoot 38 special hollow based wadcutter
  • Will shoot Black Hills' "Cowboy" 38 special ammunition

A drop-in cylinder allows you to fire centerfire ammunition in your blackpowder revolver. It will convert your blackpowder revolver to fire "Cowboy" ammunition.  You can also use .38 Special Hollow Based Wadcutter ammunition, or Black Hills’ Cowboy .38 SPL ammunition. Only top grade certified steel (4150 Steel Cylinder and 4140 Steel Top Plate) is used in the production of these cylinders to offer superior quality, strength and safety. No FFL required to purchase. Not for use in brass frame revolvers. Not available in all areas.

  • Due to manufacturing variations in revolvers, some minor fitting may be required.

The conversion cylinder has a plate at the rear of the cylinder body that contains the firing pins. The plate is removed by lifting it off the cylinder body. There is an indexing pin in the body so that the firing pins align properly with the chambers in the cylinder. Removing the plate allows access to the chambers in the cylinder body. Load the chambers with the specified caliber of ammunition. Replace the plate. Remove the original cylinder from the blackpowder handgun and replace that cylinder with the conversion cylinder. After firing, the conversion cylinder must be removed and the plate lifted off so that the empty brass can be removed with a rod or other suitable object (not included with the cylinder).

Note: This conversion cylinder is for BLACK POWDER cartridges or black powder equivalent cartridges (also called Cowboy Ammunition) with lead bullets on a steel frame revolver ONLY. Attempting to use modern ammunition and/or installation on a brass frame will create a dangerous condition that can result in injury or death. Dry firing with the conversion installed will damage the firing pins.
