Revolver

The term “Revolver” means a projectile weapon of the pistol type, having a breechloading chambered cylinder so arranged that the cocking of the hammer or movement of the trigger rotates it and brings the next cartridge in line with the barrel for firing.

For Writers: Semi-autos and fully automatic (machine guns) automatically eject spent cartridges. Revolvers DO NOT. Therefore, writers, chances are slim and mostly none of finding empty revolver cartridges at a crime scene. Please remember this when writing the “aha” moment in your WIP.
