A pistol developed in 1895 by
colt for the growing concealed-
weapon self defence industry being spawned by poor conditions in the inner cities. The parameters where simple, To create a compact pistol that would draw without catching on anything, fires a common round. The answer came in two versions, the 1903
pocket hammerless and the 1903 vest
pocket hammerless. The latter was a scaled down version. The pocket hammerless fired .32 ACP and the Vest-pocket hammerless fired .25 ACP.
Both where very sucessful, infact, the pocket hammerless survived is a browning design that was produced by Fabrique Nationale in Belgium untill 1987.
May have been one of the longest produced pistoles of all time.
