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 and far 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. As activating Dead Eye doesn't instantly reload the gun like in single player, there is no way to reload the gun quickly.
In the PC version, the LeMat Revolver can be purchased from the gunsmith in Saint Denis at anytime.
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 first weapon in Red Dead Online (and by extension, Red Dead Redemption 2) to feature a secondary firing mode. Players can alternate between revolver ammunition and shotgun ammunition at their leisure.
- The LeMat is the slowest to reload out of all revolvers found in Red Dead Online, but it compensates for this with its ammo capacity, alternating fire and strong damage.
- At $317, the LeMat is the most expensive revolver in Red Dead Online.
- Despite being 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.
