LeMat Grapeshot Revolvers: Design Evolution

Published on March 2, 2016
Duration: 20:52

This guide details the disassembly and reassembly process for the LeMat Grapeshot Revolver, as demonstrated by Ian McCollum. It covers the unique barrel threading mechanism and the evolution of the disassembly lever from an early spring-loaded type to a simpler plug system on later models. Proper safety precautions are emphasized throughout.

Quick Summary

The LeMat Grapeshot Revolver evolved significantly, with the second model simplifying manufacturing via a pull-out plug for barrel release and a left-side loading lever. Early models used a pin cylinder lockup, later replaced by a more robust wedge system for improved reliability. Barrel engravings also changed, reflecting production changes and patent information.

Frequently Asked Questions

What are the key features of the LeMat Grapeshot Revolver?

The LeMat Grapeshot Revolver is known for its unique dual-barrel design, featuring a .42 caliber percussion cylinder and an 18-gauge central shotgun barrel. It was a complex firearm with a single-action percussion mechanism, typically a 9-round cylinder capacity plus the shotgun barrel.

How did the LeMat Grapeshot Revolver evolve between its first and second models?

The second model introduced manufacturing simplifications, including removing the trigger guard spur, moving the loading lever to the left side, and replacing the disassembly lever with a simpler pull-out plug. The hammer also gained a lever for switching barrels.

What were the different cylinder lockup mechanisms used on the LeMat revolver?

Early LeMat revolvers used a pin-based cylinder lockup system. Later models, around serial number 2000, transitioned to a more reliable spring-loaded wedge system that engaged square cutouts between the cylinder's ratchet steps.

Who manufactured the early LeMat Grapeshot Revolver prototypes?

Early LeMat Grapeshot Revolver prototypes were manufactured in Belgium, notably by August Francotte, as indicated by 'AF' and 'ELG' proof marks on the firearm.
