The pinfire system was an early cartridge type which saw widespread use in Europe, but was not widely adopted in the United States. First invented by a French designer named Pauly, it was made commercially feasible by Casimir Lefacheaux. It was Casimir's son Eugene, however, who took the pinfire cartridge to its full potential, garnering a French military contract in the 1850s and building Lefacheaux into one of the largest French/Belgian non-government arms manufacturers in the mid 1800s.

Todays we are looking at an assortment of pinfire revolvers, to get some basic idea for the sort of variety that was made over the decades. Small to large, plain to fancy, and with all manner of quirky details (like folding bayonets and Lefacheaux's triple-action fire control system).
