You should always treat every gun as though it is loaded and always keep the muzzle pointed in a safe direction. Never rely upon any safety or mechanical device to justify unsafe or careless gun handling. In order to assist you in determining the presence of a cartridge in the chamber of your RUGER® MARK III pistol, it is equipped with a loaded chamber indicator, the first such device on a .22 caliber pistol. The indicator appears on the left side of the receiver. (See "Nomenclature," p. 8.)
When the chamber is empty, the loaded chamber indicator should be flush with the left side of the receiver. (See Figure 5A, p. 16.)
When the chamber is loaded, the rearmost portion of the loaded chamber indicator should protrude from the left side of the receiver, and a red dot also should be visible on the forward top portion of the loaded chamber indicator. (See Figure 5B, below.)
