The .41
rimfire is in the family of
firearm cartridges which were chambered in
derringers and
revolvers in the late 19th and early 20th centuries. The .41 rimfire family was first introduced by the
National Arms Company in 1863 as the
.41 Short, chambered in their derringer. In 1873 the slightly more powerful .41 Long was introduced in the
Colt New Line pocket revolver.[1]
