The Colt and Smith & Wesson revolvers have been made to handle the .45 caliber automatic-pistol ammunition. They may be used either as single or double action guns and each holds six rounds. In order to facilitate loading and ejection the cartridges are held in spring tempered steel clips each containing three cartridges, thereby makin it possible to load the gun with two clips of cartridges. The clips are expendable
and are ejected holding the empty shells. A shoulder in each chamber prevents the cartridges from dropping through when placed in the gun without the clips. In case this his is done, however, it will be necessary to pull the empty shell out of the chambers, since there is no rim for the ejector to force
against.

It should be remembered that the cylinder on the Colt revolver rotates in a clockwise direction, and that on the Smith & Wesson in a counterclockwise direction.
