LCR, Dardick, Thunder Five, some of the late 1800s European revolvers(not including the French model 1873 11mm). Tough choice.
The Dardick was a revolver. It had a cylinder. It had a magazine in the grip that fed the "Trounds" into the cylinder. It was one ugly trigger cocking revolver.
The Gyrojet pistol was the one that shot rockets.
