Action: The action of the Ruger SR9 pistol is of the improved striker-fired type
that utilizes a tilting barrel design in which the barrel and slide are locked
together at the moment of firing. The internal striker is partially cocked by the
action of the slide. Pulling the trigger fully to the rear completes the cocking of
the striker, releases the internal striker block, and disengages the internal trigger
safety. The last bit of trigger pull fires the pistol. After firing, the barrel and slide
recoil to the rear a short distance while still locked together. After this initial
movement, the barrel is cammed downward from its locked position, permitting
full recoil of the slide and the extraction and ejection of the spent cartridge case.
Upon return of the slide to its forward position by the recoil spring, the barrel is
cammed back upward into its locked position in the slide.
The user of this or any autoloading pistol must always remember that when
fired, it automatically reloads and recocks itself, so that simply pulling the
trigger will fire the pistol again. Therefore, an autoloading pistol user must be
particularly conscious to always keep the pistol pointed in a safe direction.
Slide Stop:
When the last shot has been fired and the magazine is empty, the
slide stop automatically holds the slide open. When there is an empty magazine
in the pistol and the slide is retracted manually, the slide stop will also
automatically hold the slide open. If a loaded magazine is inserted in the pistol
when the slide is closed and the slide is then retracted fully, the slide stop will
not automatically hold open the slide. The user can actuate the slide stop
mechanism to hold the slide open at any time by retracting the slide and pushing
the slide stop up.
The slide stop can be released by drawing back slightly on the slide and
depressing the slide stop thumbpiece. When the slide is released, it will move
forward under pressure from the recoil spring.
The slide stop is spring loaded downward. Therefore, when there is a loaded
magazine in place and the pistol is jarred, the slide can fly forward and chamber
a cartridge. For this reason and as an essential safety practice, the user should
always be careful to keep fingers away from the trigger, keep the safety on, and
always keep the pistol pointed in a safe direction.
Magazines:
The 9mm Parabellum (9mm x 19) magazines designed for the SR9
are not
interchangeable with other Ruger 9mm Parabellum magazines or Ruger
pistol magazines of any other caliber even though they may appear similar.
OPERATION OF MANUAL SAFETY
The model you have selected is equipped with ambidextrous manual safety levers.
To engage the manual safety, point the pistol in a safe dir
ection. Move either the
right- or left-hand safety lever upward and fully to the “safe” position. When the
safety is moved fully upward to the “safe” position, the red oval on the left side of
the slide will be fully covered by the left safety lever and a white dot will be
visible. If any red is showing, the safety is not in the “safe” position. Do not
attempt to engage the safety while pulling the trigger.
The safety mechanism provides that the trigger cannot be pulled unless the
safety is disengaged. Like the 1911 pistols, the manual safety lever locks the slide
