9mm Rechambering Service

This 9mm rechambering service modifies your revolver cylinder so it can accept 9mm cartridges when used with moon clips while retaining the ability to fire the original rimmed cartridge. The conversion allows reliable use of 9mm while maintaining normal function with the factory caliber.

Rechambering is performed to factory ammunition specifications only. If you reload, please send 10 cartridges with your cylinder.

Compatibility Notes

You can still shoot the original rimmed cartridge caliber without moon clips, just as you did before the modification. The machining process simply allows the cylinder to also accept 9mm cartridges when used with moon clips.

• 9mm must be used with moon clips.
• The original rimmed cartridge can still be fired individually or with moon clips.
• Rimmed cartridge brass may show slight case head bulging in converted cylinders. This only affects reloaders and does not impact function.
