Kirst Konverters

Kirst Konverters allow you to swap cylinders with most black powder revolvers and shoot .45 Long Colt, .45 ACP in a steel framed .44 cap and ball revolver and .38 special or .38 LC from a .36 cap and ball revolver. There are also conversion kits that will allow you to swap another cylinder and shoot .22 long rifle from the same revolver. 

.22 Long Rifle rounds can be fired from brass framed cap and ball revolvers.
