Lineage

History
Developed concurrently with the .41 Short for slightly larger revolvers capable of handling a longer case. Several manufacturers chambered pocket revolvers in .41 Long during the 1860s–1880s. Never achieved the widespread adoption of .44 Henry or .38 rimfire cartridges, and was rendered obsolete by the transition to centerfire in the 1880s. No current production exists; shooters with original firearms must rely on custom loads or black-powder substitutes.
