A pinfire cartridge is an obsolete type of metallic firearm cartridge in which the priming compound is ignited by striking a small pin which protrudes radially from just above the base of the cartridge. Invented by Frenchman Casimir Lefaucheux in the 1830s[1] but not patented until 1835,[2] it was one of the earliest practical designs of a metallic cartridge. Its history is closely associated with the development of the breechloader which replaced muzzle-loading weapons.
