1851 Colt Navy & 1861 Colt Navy reproduction revolver Kirst Konverters
Kirst Konverter® offers a cartridge conversion cylinder for both the 1851 and the 1861 Colt Navy revolvers manufactured by Uberti or Pietta, which is a six-shot cylinder.
We now offer two throat diameters: .357" for standard .38 caliber bullets and .375" for .38 caliber heeled base bullets. Plus we also reline barrels to .357" for those who wish to accurately shoot standard .38 caliber bullets.
These Colt Navy Konverters are designed to shoot .38 Special Cowboy ammunition not exceeding 1.425" overall length. You may also shoot .38 Long Colt and .38 Short Colt ammunition. Ammo must be loaded with lead bullets and a low-pressure, powder charge not to exceed 1000 feet per second velocity.
Simple, step-by-step instructions are included with each Kirst Cartridge Konverter for the 1851 & 1861 Colt Navy revolvers and at Colt Porting Instructions.
Caution: Ammunition must be loaded with lead bullets and a low-pressure, powder charge not to exceed 1000 feet per second velocity. Do not use the Kirst Konverter® in revolvers with a brass frame (except for .22 caliber rimfire Konverters.) Be careful to never install a .44 or .45 caliber Kirst Konverter® in a revolver with a .36 caliber barrel.
