Instruction manual

The bolt stop is spring-loaded to move downward. Therefore, when there is a
loaded magazine in place and the pistol is jarred, the bolt may 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
firing the gun at a selected target.
Magazines:
The 10-shot magazine (Part M-10) for the RUGER
®
MARK II
Standard, Target, Government Target, and Competition
Model pistols 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
these RUGER
®
MARK II pistols because it is designed to correctly function
the bolt stop. The 9-shot, AMC pistol magazine (identified by its brightly plated
non-removable bottom) and the AP-10 magazine (with its elongated plastic
bottom), which are used in other Ruger pistols should not be used in the above
RUGER
®
MARK II pistols.
The RUGER
®
22/45 pistol uses a different 10-shot magazine (part AP-10)
which is identified by its removable elongated plastic bottom. It is not
interchangeable with the M-10 or AMC magazines described above. See
“Magazine Nomenclature,” p. 24.
