.41 Remington Magnum

In 1963, Elmer Keith and Bill Jordan, with some help from Skeeter Skelton, petitioned Smith & Wesson, Remington, and Norma to produce a pistol and ammunition in .41 caliber which would fall between the extant .357 Magnum and .44 Magnum cartridges in ballistic performance, and at the same time address perceived shortcomings with those loads.

The powerful .44 Magnum, primarily a heavy hunting round, was considered overkill for police use, generating too much recoil for control under rapid fire.

In addition, the revolvers chambered for the .44 Magnum were considered too large, bulky, and heavy for police to carry.

[3][5] Additionally, Smith & Wesson had simply adapted their large N-frame revolvers for the new cartridge, which did not address size and weight concerns.

Henry Repeating Arms introduced a .41 Magnum variant of their Big Boy Steel model in 2016.
