History

Introduced around 1863 for the pocket pistol market. The Remington Model 95 double derringer — one of the most produced American handguns ever — was chambered exclusively in .41 Short for over 80 years (1866–1935). The cartridge's modest power was appropriate for a derringer: it was a contact-range self-defense round, not a fighting cartridge. CCI produced it for collectors into the modern era, though availability is now extremely limited. Antique Remington derringers chambered in this round are a staple of American arms collections.
