Ruger Sp101 Instructions Manual

							STORAGE
GUNS SHOULD NOT BE STORED LOADED!
Do notkeep your revolver in a leather, fabric or canvas holster when it is stored.
These materials attract moisture, even though the holster may appear to be
perfectly dry.
TO RENDER THE REVOLVER INOPERATIVE FOR SAFE STORAGE
With the muzzle pointed in a safe direction, press the cylinder latch and swing the
cylinder outward. Check to be sure that each chamber is completely unloaded!
With a coin or screwdriver, unscrew the grip panels and remove the grips. Cock the
hammer and then insert the disassembly pin into the hole at the bottom of the
mainspring strut. Uncock the hammer, remove the hammer strut from the frame,
remove the hammer pivot from the frame, and lift the hammer out of the top of
the frame. Use a screwdriver to depress the trigger housing latch and remove the
trigger assembly from the bottom of the frame.
Store the hammer and the trigger assembly in different locations from the frame.
When disassembled in this manner, the revolver is inoperable. It is impossible to
fire the revolver until the trigger assembly and the hammer have been correctly
reassembled into the frame.
USE THE LOCKING DEVICE SUPPLIED WITH
THE REVOLVER FOR STORAGE.

WARNING – LUBRICATION
Firing a revolver with oil, grease, or any
other material even partially obstructing the
bore may result in damage to the revolver
and injury to the shooter and those nearby.
Do not spray or apply lubricants directly on
ammunition. If the powder charge of a
cartridge is affected by the lubricant, it may
not be ignited, but the energy from the
primer may be sufficient to push the bullet
into the bore where it may become lodged.
Firing a subsequent bullet onto the
obstructed bore may damage the revolver
and cause injury 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
If lead bullet loads are fired extensively, lead build-up may cause cylinder
binding. Lubricate the cylinder crane gap with Break-Free® CLP or some other
lubrication which meets mil. spec. Mil-163460 to prevent this condition. 
						

							Never place or store any firearm in
such a manner that it may be
dislodged. 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
separate from their ammunition and
inaccessible to children and any other
unauthorized person.
STORE SECURELY & UNLOADED
23
WARNING – STORAGE
To reassemble the revolver for firing, carefully reinsert the trigger housing into
the frame. Place the hammer into the top of the frame, and reinsert the hammer
pivot pin. Cock the hammer, reinstall the mainspring strut, and remove the
disassembly pin from the mainspring strut. Lower the hammer and replace the
grips on the revolver. The revolver is now reassembled and can be loaded and
fired normally.
While the revolver is less likely to be used by unauthorized persons when
disassembled in the above manner, it is always safest to store a 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
ammunition.
CARE OF STAINLESS STEEL REVOLVERS
Revolvers made of stainless steel are more resistant to corrosion than blued steel
revolvers. However, in the interest of proper operation and long life of your
revolver, inspect it frequently and clean, lubricate and apply an appropriate rust
preventative.
Sometimes surface discoloration may be noted, particularly in the grip area of
stainless steel revolvers, resulting from perspiration. Contact with some types of
holsters can also cause stains or rusting. Rusting may also occur as a result of
the revolver being exposed to moisture, humidity, salt air or chemicals. 
						

							SIGHTS
.38 SPL, .357 Mag. & 9mm
The SP101 .38 SPL, .357 Mag. & 9mm revolvers are provided with fixed sights.
To change the front sight, drive out the pin in the barrel rib with a small punch
and lift out sight blade.
24
Rear sightSuggested sight picture
Top of front sight even with top
of rear sight. Front sight centered
in notch of rear sight. Target
bullseye centered on top of front
sight.
Minor discoloration can usually be removed by rubbing the stained area with an
abrasive ink eraser, crocus cloth, or a “metal polishing” compound. When using
any of these abrasives, proceed with care and use light pressure to achieve a
blending of ‘color’ with those areas that are not discolored.
External surfaces of the barrel, frame and cylinder should be cleaned and wiped
dry after use or after exposure to adverse conditions. If the revolver is to be
stored, coat it with a light film of oil or preservative. Where the revolver is in
continuing use, and the presence of oil or grease would be objectionable, then
the external surface can be coated (after cleaning and drying) with a paste wax
formulated for use on metals. Apply the wax sparingly, allow time for it to dry
hard, then buff lightly with a soft cloth. When applying the wax, take care that it
does not get into the mechanism or on the functioning parts such as the
hammer, trigger, crane latch, etc. A properly applied hard wax coating will not
interfere with gun handling and it will provide a measure of protection. 
						

							25
SIGHT ADJUSTMENTS
.22 LR & .32 H & R Magnum
The SP101 .22 LR & .32 H & R Magnum revolvers are equipped with sights
adjustable for windage. Each click of the rear sight adjustment screw will move
the point of bullet impact approximately 1/2” on the target at 25 yards using a 4”
barrel length.
To move the point of impact to the right: Turn the click screw counterclockwise.
To move the point of impact to the left: Turn the click screw clockwise.

St., Newport, New Hampshire 03773. Telephone (603) 865-2442.

The Federal Gun Control Act, as well as the laws of most States and localities, do
not prohibit an individual (who is not otherwise barred from purchasing or
possessing a firearm) from shipping a firearm directly to the manufacturer for
repair. However, before you ship your revolver to us, be certain that your State or
locality does not have a law or regulation which will prohibit you from receiving
the revolver from us after it has been repaired. If such receiving is prohibited,
then please have a Federally Licensed firearms dealer ship the gun to us. If your
revolver is sent to us by a dealer, it will be returned to him after being repaired.
If a handgun (pistol or revolver) is shipped by an individual who does not hold a
Federal Firearms License, it must be shipped via U.P.S. (Next Day Air) Persons
who do not hold a Federal Firearms License are prohibited by Federal law from
shipping a handgun by Mail. Handguns mailed in violation of the law are
impounded by the Post Office.
WARNING–BEFORE SHIPPING ANY
FIREARM, BE ABSOLUTELY CERTAIN THAT IT
AND ITS CYLINDER ARE UNLOADED. DO
NOT SHIP CARTRIDGES WITH A FIREARM.

COLLECTOR’S ITEMS – THESE ARE INVARIABLY DAMAGED OR
DESTROYED IN SHIPMENT.Please do not include holster, grip panels, or other
accessories with a firearm being shipped to the factory for service. Always insure
your shipment.
Enclose a letter which includes your name, address, telephone number, serial
number and model of the firearm. Describe in detail the trouble you have
experienced with your firearm, or the work you wish to have done. Merely stating
that the firearm “needs repair” is inadequate information.

shipping and handling charge. The charge for metal refinishing the RUGER
®
SP101revolver is $50.00 plus a $20.00 shipping and handling charge. Custom

WARNING – PARTS PURCHASERS
It is the purchaser’s responsibility to be
absolutely certain that any parts ordered from the

FITTING OF PARTS MAY RESULT IN A
DANGEROUS MALFUNCTION, DAMAGE TO
THE FIREARM, AND SERIOUS INJURY TO THE
SHOOTER AND OTHER PERSONS. The
purchaser and installer of parts must accept full
responsibility for the correct adjustment and
functioning of the revolver after such installation.
PARTS MUST FIT CORRECTLY 
						

							27
Barrels, cylinders, cylinder/crane assemblies and a number of other component
parts must be fitted at the factory. Company policy is to proof-test and/or
function fire all barrels after fitting to the frames in which they are to be used.
This procedure ensures maximum protection to our customers. The special
proof-test ammunition used in this testing is sold only to bonafide firearms
manufacturers and is not available to gun shops, gunsmiths, or individuals.
Because the frame of the RUGER
®SP101 revolver is a serial numbered
component, it is defined as a “firearm” by Federal law and is not sold as a
separate component.
*Parts designated by an asterisk must be factory fitted. These parts are fitted on
an exchange basis only. We will not return the replaced parts. We will not return
any part that is broken, malfunctioning, badly worn or has been modified. See
“Warning – Parts Purchasers”, p. 26.
CAUTION: A gun containing modified, broken,
malfunctioning, or badly worn parts should not be fired.
