History
Introduced alongside the .38 Short Colt in 1875 for the smallest frame Colt double-action revolvers. The .32 Short Colt was positioned as a pocket and ladies' defense cartridge — light recoil, compact revolvers, minimal noise. Its energy levels were barely above those of the .22 rimfire family it notionally replaced. The .32 Long Colt offered meaningfully better performance and rendered the Short obsolete within a decade. No current commercial production; original Colt Rainmaker and similar pocket revolvers are collected as curios.
