The .41 Action Express was developed by Evan Whildin and Action Arms for the Jericho 941 as a high-velocity 10mm-diameter cartridge with a rebated rim that allowed conversion from 9mm using only a barrel swap. The .41 AE offered .44 Magnum ballistics from a double-stack pistol magazine. Commercial failure of the .41 AE made this configuration rare in the US market, and it is now among the most collectible Jericho variants.
