I recently picked up this pair of pinfire pistols designed by Casimir Lefaucheux. I had never seen examples quite like them before and was really excited to get them in. Casimir Lefaucheux was making pistols from the time he took over the Pauly company in 1827 as shown in our recent post on the topic. But these early pistols were much larger and bulkier. In 1833, Lefaucheux was issued a new patent for his fusil à charnière, or hinged gun.
He advertised and promoted the fact that these pistols and rifles were easier to use and safer and better in every way than his earlier Pauly guns, and especially better than other percussion guns of the day. They could shoot 500 rounds without cleaning or even wiping down which was unheard of for typical percussion guns that loaded from the muzzle. Lefaucheux also emphasized that they were easier to take apart and maintain by the average person.
