The LeMat is a cap and ball revolver with a single-shot, smooth bore barrel of buckshot beneath the main barrel. Its damage and accuracy are on par with the Schofield Revolver, if not better, and superior to that of both the Double-action and Cattleman revolvers. However, its rate of fire is slower than both the Double-action and Cattleman revolvers, as is the reload speed. Its reload speed is perhaps its main flaw, being slower than any other sidearm, which is exacerbated whilst dual-wielding.
In Red Dead Redemption 2, the LeMat Revolver can be purchased from the gunsmith in Saint Denis after the mission A Fine Night of Debauchery.
In Online, the revolver can also be purchased from any gunsmith or from the handheld catalogue that the Online protagonist carries on-hand.
- The LeMat Revolver is the only weapon in the Redemption saga to feature a secondary firing mode. Players can alternate between revolver ammunition and shotgun ammunition at their leisure.
- At $317, the LeMat is the most expensive revolver in both Redemption 2 and Online.
- Despite being primarily a cap and ball revolver, the reload animation for the LeMat is the same as the other in-game revolvers, which are cartridge firing revolvers. The same was seen in the previous game's model. There were cartridge firing LeMat revolvers in existence, however they looked a bit different from ball and cap version the in-game model is based on: they had a distinct, shorter cylinder and the Belgian centerfire variant also had a different grip.
- The LeMat is the only weapon that can be upgraded to a full 4.0 stats condition.
