Black Powder Accessories/Conversion Cyls
offers conversion cylinders for the Pietta percussion revolvers from
two different manufacturers, Kirst Company, and Howell Old West
Conversions, LLC (formerly R & D). While both companies offer
conversion cylinders that enable you to switch your favorite cap &
ball replica revolver to cartridge and back, they differ in their
methodology. These conversion cylinders are designed to be used in
steel framed revolvers with black powder or equivalent cartridges,

cylinder. Each chamber has it's own firing pin. Both the back plate
and cylinder rotate together as one unit.

for use with their percussion cylinder. When changing from black powder
to cartridge ammo, the timing on your revolver may need to be
adjusted. E.M.F. Company, Inc. does not have a manufacturer's license
and therefore, is unable to fit these cylinders, modify the revolver's
frames, or change the timing on these revolvers from percussion to
Use only cowboy ammunition that does not exceed 850
FPS; never use hot or jacketed ammunition. Cowboy ammunition is
produced by most manufacturers.
Additionally, we have cylinder inserts that convert your .45LC single action revolver to accept .22 Acorn or Ramset blanks.
Converters should never be used in Brass Frame Revolvers.
