View Full Version : Kirst Cylinder

Does the installation of a Kirst 45 LC cylinder require any modification to an 1858 Remington that would make switching back to a regular percussion type cylinder a problem?

Well you an grind a loading channel behind the cylinder of the gated model to facilitate cartridge loading but; even then, the Kirst conversion is designed to allow the use of either cartridge or percussion cylinders so the answer is no, the Kirst unit just drops in just like a percussion cylinder.

Doesn't this assume all 1858 reproductions are all dimensionally the same? Cylinder diameter, length, frame window dimensions, base pin diameter, identical hands and ratchets, etc? Ubertis, Piettas, etc? 1970s, 1980s, 1990s, etc? How would one know ahead of time which manufacturer and from which decade would be compatible with any given "drop-in" conversion unit? I've been curious about this myself.

Each manufacturer has it's own part # from Kirst for the cylinder conversion.

There is a fellow on The High Road that installed either a Kirst or a R&D conversion cylinder on his Pietta NMA & performed the loading gate process & all he had to do to get the conversion cylinder to function 100% was to trim a little on the front of the cylinder.

I know it's there but for the life of me I can't find the thread.. :(

I have a Armi San Paolo 1858 and used the Kirst made for a Uberti.It fit right in with no fitting needed.I did not get the loading gate,so did not have to do any grinding on my shooter.Sure I have to take out the cylinder to reload but that is easy. I can pop in the C&B cylinder as easy as the cartridge cylinder and vis-a-vis.
Mine is The old style that holds 5 and does not have the safety or whatever they call it chamber area.
