GENERAL INFORMATION AND MECHANICAL CHARACTERISTICS

The Ruger Mark II Standard and Mark II Target Models are .22 caliber rimfire, 10-shot, magazine-fed, semi-automatic recoil ('blowback') operated pistols. Both models have the same basic operating mechanism and include the following features with which the gun user should be thoroughly familiar.

Bolt Stop: The boh hold-open mechanism is actuated by the follower button (left side of magazine) when the button is in its topmost position. Thus, when the last shot has been fired and the magazine is empty, the button moves the bolt stop to hold the bolt open. When there is an empty magazine in the pistol and the bolt is retracted manually, the bolt stop will automatically hold the bolt open. If there is a loaded magazine in the pistol or if there is no magazine in the pistol, the user can actuate the bolt stop mechanism to hold the bolt open by retracting the bolt and pushing up the bolt stop.

If there is an empty magazine in place, the bolt stop can be released by drawing back slightly on the bolt and depressing the bolt stop thumbpiece. When the bolt is released, it will move forward under pressure from the recoil spring.

NOTE: If a loaded magazine is inserted in the pistol when the bolt is closed and the bolt is then retracted fully, the bolt stop will not automatically hold open the bolt. However, in such a situation the bolt stop can be manually actuated, by pushing the thumbpiece upwards, to hold the bolt open.

WARNING: The bolt stop is spring-loaded to move downward. Therefore, when there is a loaded magazine in place and the pistol is jarred to the extent that the bolt moves rearward, releasing tension on the bolt stop, the bolt will fly forward and chamber a cartridge. For this reason and as an essential safety practice, the safety of the pistol should always be in the on ("S") position except when the user is positioned to fire the gun at a selected target.

Safety: The safety locks the sear when the safety is "on". Because the safety cannot be moved to "on" ("S" position) unless the hammer is cocked, the safety therefore serves as a cocking indicator. Most importantly, the bolt can be manually retracted and released when the safety is "on" (S). This highly desirable feature allows the pistol to be loaded or unloaded and allows a cartridge to be chambered when the safety is "on" (S). As noted above and elsewhere in this Manual, the safety should be "on" (the "S" fully showing) at all times except when the gun user is deliberately positioned to fire at a selected target See Figures 1 and 2 which illustrate the two positions — "S" and "F" — of the safety.

Magazine: The.JO-shot magazine (Part M-10) for the Mark II pistol is readily identified by the removable plastic bottom decorated with a silver'eagle'. The M-10 is the only magazine which should be used in a Mark II pistol because it is designed to correctly function the bolt stop. The parts drawing (page 16) illustrates how easily the M-10 can be disassembled for cleaning. WARNING: The standard 9-shot, AMC pistol magazine (identified by its non-removable bottom), which is used in Ruger pistols other than the Mark II, should not be used in the Mark II because its follower button will activate the Mark II bolt stop before the last cartridge is stripped from the magazine. Although the 10-shot, M-10 magazine and the 9-shot, AMC magazine are interchangeable in that they will fit into the magazine-well of most Ruger Automatic Pistols, users are warned that "mixing" these magazines of different cartridge capacity can create an unsafe situation. Therefore, do not use an M-10 magazine in pistols designed for use with the AMC magazine, and do not use the AMC magazine in Mark II pistols.

Don't rely on your memory to know if a gun or magazine is loaded. Visually inspect the magazine and the chamber.

WARNING: So that the pistol can be used as a single loader, these pistols will fire whether or not there is a magazine in the gun if there is a cartridge in the chamber. Removing the magazine does not unload the pistol. To unload the pistol, FIRST REMOVE THE MAGAZINE, THEN PULL BOLT FULLY TO THE REAR AND EJECT THE CARTRIDGE. DON'T ASSUME THAT THE CHAMBER IS EMPTY, VISUALLY INSPECT IT EVERY TIME YOU HANDLE THE PISTOL.
