Ruger Carbines PS9 Instruction Manual

							So that the rifle can be used as a single loader, it
will fire whether or not a magazine is in the gun
if a cartridge is chambered. Removing magazine
does not unload rifle! To unload, first remove
magazine, then pull slide to rear, eject chambered
cartridge, and visually inspect chamber. The safety
should always be in the “on” (safe) position when
loading or unloading the rifle.
GUN WILL FIRE WITH
MAGAZINE OUT

TO LOAD AND FIRE (WITHOUT MAGAZINE)
The rifle can be used as a single shot rifle in the absence of a magazine or for
safety or training purposes. To do so, follow steps 1 and 2, p. 9. Then load a car-
tridge into the chamber, and follow steps 7 and 8, p. 10, disregarding the maga-
zine. Engage the safety between shots.
!WARNING – UNLOADING
TO UNLOAD
NOTE:This sequence must be followed exactly as spelled out. Failure to do so
can result in the rifle’s chamber becoming unintentionally loaded with a car-
tridge!
!WARNING – HANDLING
SAFETY IN THE“OFF” (FIRE) POSITION
If dropped or
struck with the
safety “off”, the
rifle may fire.
Keep chamber
empty unless
actually firing!
Keep safety “on”
unless actually
firing!

6. Cartridges can be removed from the magazine by simply pushing them lightly
downward and forward with the thumb, forefinger, or the rubber eraser end of
a pencil against the base of the top cartridge. Do not use a loaded cartridge as a
‘tool’ to strip cartridges from the magazine.
7. If desired, the slide can be left in the open position, being held there by the
slide stop. If it is desired to close the slide, again look to be certain the cham-
ber is empty. Keep the safety “on”, retract the slide to its rearmost position,
push the thumbpiece of the slide stop down, and let the slide snap forward.
Keep your fingers out of the receiver!
8.With the muzzle pointed in a safe direction,push the safety to the “off” posi-
tion and pull the trigger to decock it. The rifle can be “dry fired” for practice as
long as it is empty and pointed in a safe direction.
9. Push empty (unloaded) magazine into the rifle until the magazine latch locks
it in place. If an empty magazine is inserted into a rifle with the slide held
open, it will be necessary to press the bolt stop downward in order to close the
slide.
1. Keep the muzzle pointed in a safe direction at all times and keep the fingers
outside the trigger guard. Move the safety to the “on” position.
2. Remove the magazine. Rememberthat even though the magazine has been
removed, a cartridge remaining in the chamber can still be fired!
3. Retract the slide to its open position and hold it open by pressing the slide
stop up.
4.Always visually double check the chamber to be certain it is empty.
5. The only “safe” rifle is one in which the slide is open, the chamber is empty,
and there is no magazine in the gun.

TO EXTRACT AND EJECT
ACHAMBERED CARTRIDGE
When the rifle is fired, the same gas pressure which drives the bullet forward also
acts through the cartridge case to push the slide to the rear. That action causes
extraction and ejection of the fired cartridge case. But, when the slide is operated
by hand, there can be a failure to extract the cartridge from the chamber, or a
failure to eject the cartridge clear of the rifle. These failures usually are the result
of the slide not being pulled rearward vigorously, coupled with an accumulation
of firing residue in the chamber. From the foregoing it is clear that the gun user
must:
1.Always visually check the chamber after opening the slide to eject a chambered
cartridge.If the slide is not vigorously retracted when being operated by hand,
the extracted cartridge can be ‘ejected’ into the magazine area, instead of out-
side the rifle. (Remember that the magazine should be removed prior
to
unloading the chamber.)
2. Thor
oughly clean the chamber and the extractor as often as necessaryto pre-
vent the accumulation of grease and dirt.
3. If an empty magazine is in the rifle when the slide is being hand retracted to
extract a cartridge, the cartridge may drop on top of the magazine. Then when
the slide goes forward, the cartridge will be chambered again! Always remove
the magazine before clearing the chamber, and visually ensure that no car-
tridges remain in the gun.
TO CLEAR A MALFUNCTION (“JAM”)
Any autoloading firearm may occasionally malfunction. If it does:
1.Be certain the muzzle is pointed in a safe direction and the safety is “on”.
2. If possible, remove the magazine. It may be necessary to manually remove a
jammed cartridge which has only partially been stripped from the magazine. If
so, use extreme care. Hold the slide open with the slide stop before attempting
to clear the jam. Drawing the slide fully to the rear may bring the jammed car-
tridge along. Keep your face away from the ejection port during this operation.
When attempting to clear a jam, use only wood ‘tools’ so that a cartridge will
not be ignited if you strike a primer and so that the chamber and magazine
will not be damaged. A 3/16” wood dowel rod with a point on one end is useful.
3. Visually check to make sure all cartridges have been removed from the rifle.
Safely dispose of any cartridges involved in a malfunction incident. Do not use
damaged ammunition in any firearm.
TO MINIMIZE MALFUNCTIONS (“JAMS”)
Most malfunctions are caused by improper or damaged magazines, incorrect
ammunition, or poor maintenance. 
1. If it appears that the gun and magazine are not at fault and that the jam was
caused by the type of cartridge being used, then try another type. 
						

							A cartridge fires when the firing pin impacts the primer,
and also can be “discharged” before it is chambered if its
primer receives a sharp blow. If a cartridge hangs up,
jams, or binds when being chambered or when being fed
from the magazine into the chamber, do not attempt to
force it into the chamber by pushing or striking the cock-
ing handle.Any jam or feeding problem is a signal to
immediately stop  using the gun until it can be deter-
mined what is wrong. Most failures of a cartridge to feed
or to chamber are caused by a damaged magazine,
improper gun handling, or defective ammunition.
Whatever the cause, cartridge jams can result in the
potentially dangerous situation of a cartridge discharging
before it is chambered. If this occurs, the cartridge case
will rupture and its fragments will fly out of the gun with
sufficient force to cause injury. Always wear shooting
glasses and hearing protectors! Keep face away from
chamber!

CAN BURST CARTRIDGE

2. If changing to another type or brand of cartridges does not at once eliminate
malfunctions, then the following steps should be taken:
a. Make certain the gun and the magazine are unloaded and that the safety
is “on”. Remember, the magazine should be removed first, then check the
chamber and be certain it and the magazine well are clear of cartridges.
b. Thoroughly clean the magazine and slide mechanism, paying particular
attention to removing accumulated grease. Use a bristle brush and solvent
to remove grease and fouling from the slide, the extractor, the chamber, and
the feed ramp. (See the “Care and Cleaning” section of this manual for
detailed cleaning instructions).
c. Check to see that the magazine spring tension is adequate and that the
magazine follower moves freely up and down.
d. Check the magazine lips to be certain they are free of nicks and burrs and
are not deformed.
e. Remove excess oil and solvent from all cleaned components, load the
magazine, and try the firearm again. As always, proceed slowly. Be certain
bystanders are not close and that you are wearing eye and hearing protec-
tion and that your face is a safe distance from the rifle so that any discharge
resulting from a jammed cartridge will not injure anyone.
If the above procedures do not result in a smooth and reliably functioning
firearm, don’t use the gun. The rifle can be returned directly to our Prescott,
Arizona Service Department for repair. See the “Service and Parts Policy” section
of this manual for packing and shipping information.
Another precaution:When using any autoloading firearm, form the habit of
examining fired cartridge cases. If they have bulged heads or frequently show
splits on any part of the case, the rifle should be returned to the factory for
inspection.

Note:If bolt is not held open slightly while lowering barreled action into stock,
it will be impossible to operate action! If this occurs, simply lift the action
slightly out of the stock, retract the bolt slightly, and keep it open as you lower
the action back into the stock. Once the barrel/receiver assembly is in place in
the stock, replace the take down screw and lock washer. While replacing the
take down screw and lock washer, ensure that the receiver spacer is in place
inside the stock if your carbine is so equipped. (See Fig. 14)

							MAGAZINE INSPECTION AND CARE
Check the magazine frequently. The magazine follower must move freely and
have adequate spring tension so that each cartridge is quickly raised to the feed-
ing position. The magazine lips should be clean and free of cracks, dents, or
nicks, so that cartridges are held in their proper feeding position.
If the magazine becomes dirty, it should be disassembled and thoroughly
cleaned. You could encounter two types of Ruger magazines, with either a pinned
base or a snap-on base. The following disassembly instructions apply:
Pinned Base(used on 10 round 9mm magazines) - Use a punch to remove the
roll pin that extends through the side of the magazine body. Once the roll pin
has been removed, pull the magazine base from the bottom of the magazine
body, taking care to prevent the forcible ejection of the compressed magazine
spring. Withdraw the magazine spring from the magazine body. Turn the maga-
zine upside down and remove the follower.
Snap-On Base- Use a punch to press in on magazine spring seat where it pro-
trudes into the hole in the magazine floorplate. Slide the magazine floorplate
toward the rear of the magazine, taking care to prevent the forcible ejection of
the magazine spring seat and compressed magazine spring. Withdraw the maga-
zine spring seat and magazine spring from the magazine body. Turn magazine
upside down and remove magazine follower. Reassemble in reverse order.
When cleaning is necessary, use a solvent that will not rust the metal compo-
nents or adversely affect the magazine follower. After the magazine has been
soaked in solvent to loosen foreign matter, be certain to shake it vigorously (with
the loading opening away from you) to remove solvent or residue from within
the magazine. Penetrating oils and solvents inside a magazine can “kill” or weak-
en cartridge primers, which can result in failures to fire or other possibly danger-
ous malfunctions, such as leaving a bullet in the bore!
After cleaning, always check to be certain that the magazine follower movement
and spring tension are correct, and that no solvent or debris remain. Improper
reassembly of the magazine spring can cause a potentially dangerous malfunc-
tion.  If cleaning does not restore proper tension, or if you experience a problem
with the magazine, don’t use it. Get a new one.
CARE AND CLEANING
Make Sure Gun Is Unloaded!
Before cleaning, be certain the rifle and its magazine contain no cartridges (see
“To Unload”, p. 11).
At regular intervals, or whenever the rifle has been exposed to sand, dust,
extreme humidity, condensation, immersion in water, or other adverse

DAMAGED, NON-STANDARD, OR IMPROPERLY
ASSEMBLED MAGAZINES SHOULD NOT BE USED.
THEY CAN CAUSE THE RIFLE TO MALFUNCTION.

3. Using powder solvent on a clean patch or bristle brush, remove powder
residue from all components of the mechanism. After cleaning, run a dry
patch through the bore, then follow with a patch that is very lightly oiled.
Wipe all surfaces clean with a cloth, then wipe all surfaces with a patch or
cloth that has been very lightly oiled.
4. NOTE: Only a light application of oil or grease is needed to provide adequate
lubrication of moving parts and to prevent rust. Excess accumulations of oil
tend to attract particles of dust and dirt and may congeal in cold weather
which can interfere with the safe and reliable function of the rifle.
STORAGE
GUNS SHOULD NOT BE STORED LOADED!
USE THE LOCKING DEVICE SUPPLIED WITH THE RIFLE FOR STORAGE.
(SEEPAGE2)
Do notstore the rifle in a leather case or scabbard. Leather attracts moisture,
even though it may appear to be dry.
conditions, disassemble, clean and oil it. Proper periodic maintenance is essential
to the reliable functioning of any firearm.
To clean the rifle, proceed as follows:
1. Disassemble (field-strip) the rifle to the extent described on pages 15 & 16.
2. Using a cleaning rod, run a solvent-wetted patch through the bore several
times. Then attach a solvent-wetted bristle brush to the rod and run it back
and forth the full length of the bore as many times as necessary to remove
grease and dirt from the bore and chamber. Clean bore with dry patches and
examine. Bore fouling can contribute to reduced accuracy, and grease accumu-
lation in the chamber can interfere with proper feeding of cartridges from the
magazine.
!WARNING – LUBRICATION
OIL
Firing a rifle with oil, grease, or any other material
even partially obstructing the bore may result in dam-
age to the rifle and  serious injury to the shooter and
those nearby. Do not spray or apply lubricants directly
on ammunition. If the powder of a cartridge is affected
by the lubricant, it may not be ignited, but the primer
firing may push the bullet into the bore where it may
be lodged. Firing a subsequent bullet into the
obstructed bore may damage the rifle and cause seri-
ous injury or death to the shooter and those nearby.
Use lubricants properly. You are responsible for the
proper care and maintenance of your firearms.
IMPROPER LUBRICATION
DESTROYS GUNS 
						

							TO RENDER THE RIFLE INOPERATIVE FOR SAFE STORAGE
With the muzzle pointed in a safe direction, remove the magazine, open the bolt,
and check the chamber to be sur
e the rifle is completely unloaded!Loosen barrel
band screw and slide barrel band forward off stock. Unscrew and remove take-
down screw on underside of stock. Carefully lift barrel/receiver assembly out of
the stock. Pull slide assembly to the rear far enough to expose cross hole in the
guide rod. Insert a pin/punch to hold slide in this position, and then allow slide
assembly to move forward to disengage guide rod. Now rotate the assembly
downward out of the receiver. Reassemble rifle without slide housing assembly,
which contains the bolt and most of the firing mechanism.
Store the rifle and the slide housing/bolt assembly in different locations. When
disassembled in this manner, the rifle is inoperable. It is impossible to fire the
rifle until the slide housing/bolt assembly has been correctly replaced into the
rifle.
To reassemble the rifle for firing, remove the barrel/receiver assembly from the
stock as above and reinstall the trigger housing/bolt assembly (see pages 16 - 17
of this manual). Carefully reinstall the barrel/receiver/trigger housing assembly
into the stock. Check to be sure the bolt, trigger, and safety mechanisms can be
operated fully and freely. The rifle is now reassembled and can be loaded and
fired normally.
While the rifle is less likely to be used by unauthorized persons when disas-
sembled in the above manner, it is always safest to store any firearm with the
supplied locking device correctly installed or to store the firearm in a gun safe
or other secure location, away from children and unauthorized adults. Guns
should always be stored securely, unloaded
and separate from their ammuni-
tion.
20
Never place or store any firearm in
such a manner that it may be dis-
lodged. Firearms should always be
stored securely and unloaded, away
from children and careless adults. Use
the locking device originally supplied
with this firearm for storage.
The use of a locking device or safety
lock is only one aspect of responsible
firearms storage. For increased safety,
firearms should be stored unloaded and
locked in a location that is both sepa-
rate from their ammunition and inac-
cessible to children and any other
unauthorized person.
STORE SECURELY & UNLOADED
