State-By-State Warnings Certain states require by law that their own specified warning notices in larger-than-normal type be conspicuously included by the manufacturer, distributor, or retail dealer with firearms sold in that state. Sturm, Ruger sells its products in compliance with applicable laws and regulations. Because our products may be sold in these states, we include the following: California: WARNING ADVERTENCIA “A los niños los atraen las armas de fuego y las pueden hacer funcionar.
Maine: “ENDANGERING THE WELFARE OF A CHILD IS A CRIME. IF YOU LEAVE A FIREARM AND AMMUNITION WITHIN EASY ACCESS OF A CHILD, YOU MAY BE SUBJECT TO FINE, IMPRISONMENT OR BOTH. KEEP FIREARMS AND AMMUNITION SEPARATE. KEEP FIREARMS AND AMMUNITION LOCKED UP. USE TRIGGER LOCKS.” Maryland: “WARNING: Children can operate firearms which may cause death or serious injury.
New Jersey: “IT IS A CRIMINAL OFFENSE TO LEAVE A LOADED FIREARM WITHIN EASY ACCESS OF A MINOR.” New York City: “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 OTHER UNAUTHORIZED PERSONS.
WHY ARE WE INCLUDING A FIRED CARTRIDGE CASE WITH EVERY RUGER PISTOL AND REVOLVER? Certain states and jurisdictions now require that all newly manufactured pistols and revolvers must be accompanied by a cartridge case, which has been test fired from that gun at the factory. The case must be placed in a sealed container bearing certain information concerning this test cartridge.
Use the Correct Lock: While the basic locking device is substantially similar for all Ruger® firearms, due to the different shapes of the many Ruger® firearms, some firearms utilize different locking devices. The lock with a 1 1/2” shackle is for use with RUGER® MARK IIITM & 22/45 MARK III Model Pistols. It is very important to use the correct locking device! To Install the Factory-Supplied Locking Device: 1.
FIREARMS SAFETY-YOUR RESPONSIBILITY SAFETY MUST BE THE FIRST AND CONSTANT CONSIDERATION OF EVERY PERSON WHO HANDLES FIREARMS AND AMMUNITION. This Instruction Manual is designed to assist you in learning how to use and care for your RUGER® MARK IIITM pistol properly. Please contact us if you have any questions about it. Only when you are certain you fully understand the Manual and can properly carry out its instructions should you practice loading, unloading, etc. with live ammunition.

The RUGER® COMPETITION MODEL MARK III has a slab-sided, heavyweight barrel with target grips. The RUGER® 22/45 MARK III has a grip frame assembly made of molded synthetic polymer, with a grip shape and angle generally similar to “1911”-style .45 caliber pistols. RUGER® MARK III HUNTER models feature a 6 7/8” target-crowned, fluted bull barrel, a micro-adjustable V-notch rear sight, and a HiViz® lightgathering front sight.
Safety: The safety locks the sear when the safety is “on.” Because the safety cannot be moved to its “on” (S) position unless the hammer is cocked, the safety therefore serves as a cocking indicator. The bolt can be manually retracted and released when the safety is “on” (S). This feature allows the pistol to be loaded or unloaded when the safety is “on” (S).
OPERATION OF INTERNAL LOCK Never rely upon any safety mechanism or mechanical device to justify unsafe or careless handling of a firearm. When securing your pistol or to prevent unauthorized access, you should completely unload the pistol and store it in a gun safe or use the key-operated external locking device supplied with your pistol. (See Page 6.) However, for added security, and to comply with certain state and local laws, your RUGER® MARK III pistol is also equipped with an internal lock.
AMMUNITION The RUGER® MARK III pistol is chambered only for the .22 caliber Long Rifle cartridge, standard velocity or high velocity, manufactured to U.S. Industry Standards. Do not attempt to load .22 Long, .22 Short, or any other type .22 caliber cartridge into the magazine or in the chamber of the pistol. Use of .22 shot shells is not recommended. See “Warning - Malfunctions,” p. 21.
TO LOAD AND FIRE Practice this important aspect of gun handing (with an unloaded pistol) until you can perform each of the steps — described below — with skill and confidence. But before you do anything with the pistol, first read completely through this manual. 1. Keep the muzzle pointed in a safe direction. (See Rule 2, p. 42.) 2. Push the magazine release button and pull the magazine down out of the grip frame by its foot. 3.
Once the safety is pushed down so the “F” shows, the pistol will fire a cartridge each time the trigger is pulled, until all of the cartridges in the magazine, and the one in the chamber, have been fired. KEEP SAFETY ON 8. The pistol is ready for instant use once the safety is disengaged. Firing will automatically reload and recock the pistol.
WARNING – HANDLING If dropped or struck with the safety “off,” the pistol may fire. Keep chamber empty unless actually firing! Keep safety “on” unless actually firing! ANY GUN MAY FIRE IF DROPPED 10. When the last cartridge loaded into the pistol has been fired, the magazine follower presses the slide stop upward to engage the slide automatically holding the action open.
When the chamber is loaded, the rearmost portion of the loaded chamber indicator should protrude from the left side of the receiver, and a red dot also should be visible on the forward top portion of the loaded chamber indicator. (See Figure 5B, below.
and briskly retract the bolt to its rearmost position. As the bolt nears the end of its retraction, the chambered cartridge should be extracted and ejected. When the bolt is fully retracted, push upward on bolt stop with thumb, then allow bolt to move forward slowly until it comes to rest against the bolt stop. Always visually double check the chamber and the interior area of the receiver and the magazine-well to be certain there are no cartridges present.
4. If desired, the bolt can be left in the open position, being held there by the bolt stop. If it is desired to close the bolt, again look to be certain the chamber is empty. Assuming that the magazine is not in the pistol and that the safety is “on” (S), retract the bolt to its rearmost position, release it, and the bolt will snap forward (on Mark III models). On 22/45 models the bolt stop button must be depressed. Keep your fingers out of the receiver! 5.
TO CLEAR A MALFUNCTION (“JAM”) 1. Be certain the muzzle is pointed in a safe direction and the safety is “on” (S). 2. If possible, first 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. Lock the bolt open with the bolt stop before attempting to clear the jam. Drawing the bolt fully to the rear may bring the jammed cartridge along. Keep your face away from the ejection port during this operation.
a. Make certain the gun and the magazine are unloaded and that the safety is “on” (S). 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 bolt mechanism, paying particular attention to removing accumulated grease. Use a bristle brush and solvent to remove grease and fouling from the bolt face, the extractor, the chamber, and the feed ramp.
WARNING – DISASSEMBLY 2 Always unload a firearm before cleaning, lubrication, disassembly or assembly. 3 1 UNLOAD BEFORE CLEANING 2. Insert a blunt, ‘pointed’ instrument in the oval recess of the mainspring housing (at the back of the grip) and swing the housing latch open like the blade of a pocket knife. (Some users find that a paper clip, looped over the latch, is an ideal ‘instrument’ for this phase of disassembly.) 3.
If you cannot place the hammer in the horizontal position, it is most likely because the hammer strut is trapped behind the crosspin (see Figure 7 – not applicable to 22/45 models). If this occurs, lift the hammer to free the hammer strut from behind the crosspin and then move the hammer into the horizontal position. HAMMER STRUT CROSSPIN If the hammer has been rotated too far forward, it also may be difficult to rotate backwards.
5. NOTE: Before sliding the Figure 10 FIRING bolt into the receiver, BE PIN STOP CERTAIN that the firing pin stop (part number A03500, a small pin) is in the bolt. (See Figure 10.) Without this pin, the first time the trigger is pulled on an assembled pistol, the firing pin will fly forward so far as to irreparably dent the rear end of the chamber of the barrel, making the pistol useless. Now, slide the bolt (with the recoil spring upward) fully forward into the receiver. (See Figure 10.) 6.
While holding the pistol in this position and depressing the trigger, move the mainspring housing into its proper place in the frame. (See Figure 13.) Figure 13 7A. For 22/45 models ONLY: Now invert the pistol so that the muzzle is pointed upward. Make sure you can see the hammer strut when you lift the housing up. The hammer strut should go into the oval-shaped cutout inside the mainspring housing (see Figure 12).
MAGAZINE NOMENCLATURE FOR 22/45 ONLY FOR ALL OTHER RUGER MARK III PISTOLS MAGAZINE DISASSEMBLY TO DISASSEMBLE MAGAZINE: Withdraw magazine from pistol and remove all cartridges (check chamber to be certain no cartridge remains in it). Hold magazine upside down in left hand so that the hole in the Magazine Block is accessible. 1. With right hand, insert drift punch in hole and depress Magazine Block Retaining Plunger approximately 1/4". 2.
MAGAZINE DISASSEMBLY 5 Remove Follower 2 Slide Block Forward 4 1 Remove Button Push Up 3 Remove Spring & Plunger DAMAGED, NON-STANDARD, OR IMPROPERLY ASSEMBLED MAGAZINES SHOULD NOT BE USED. THEY CAN CAUSE THE PISTOL TO MALFUNCTION. CARE AND CLEANING Make Sure Gun is Unloaded! Before cleaning, be certain the pistol and its magazine contain no cartridges. (See “To Unload,” p. 18.
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 is needed to provide adequate lubrication of moving parts and to prevent rust.
place. Place the safety in the “off” (F) position. Point the pistol in a safe direction and pull the trigger to uncock the pistol. Using a paper clip or similar non-marring tool, pull down on the main spring housing latch located at the lower rear of the pistol grip. Swing the main spring housing upward. With the pistol pointed upward, pull the trigger. Now invert the pistol so that it is pointing downward.
SIGHT ADJUSTMENT The Standard RUGER® MARK III pistol is equipped with a rear sight which is adjustable for windage only. The rear sight can be drifted laterally in its dovetail on the top of the slide by tapping it with a wooden or plastic headed hammer or similar implement. The front sight is fixed. Target models are equipped with adjustable sights. Turning the top (elevation) sight adjustment screw clockwise lowers the impact of the shot.
INSTRUCTIONS FOR ATTACHING THE SCOPE BASE (Target Model Only) 1. Remove the filler screws from the top of the receiver. 2. Degrease the screw holes in the receiver. 3. Degrease the scope base screws. 4. After the degreased areas are dry, place a drop of red LOCTITE adhesive/sealant or equivalent to the scope base screws. 5. Set the scope base on the receiver with the side notch aligned with the ejection port of the receiver. 6. Install the scope base screws and tighten. 7.

THE BASIC RULES OF SAFE FIREARMS HANDLING We believe that Americans have a right to purchase and use firearms for lawful purposes. The private ownership of firearms in America is traditional, but that ownership imposes the responsibility on the gun owner to use his firearms in a way which will ensure his own safety and that of others. When firearms are used in a safe and responsible manner, they are a great source of pleasure and satisfaction, and represent a fundamental part of our personal liberty.
A safe direction must take into account the fact that a bullet may penetrate a wall, ceiling, floor, window, etc., and strike a person or damage property. Make it a habit to know exactly where the muzzle of your gun is pointing whenever you handle it, and be sure that you are always in control of the direction in which the muzzle is pointing, even if you fall or stumble. Keep your finger off the trigger until you are ready to shoot. 3. FIREARMS SHOULD BE UNLOADED WHEN NOT IN USE.
5. BE SURE OF YOUR TARGET BEFORE YOU SHOOT. Don’t shoot unless you know exactly where your bullet is going to strike. Be sure of the bullet stop behind your target, even when dry-firing with an unloaded gun. If you are in the field hunting, do not fire at a movement or noise. Take the time to be absolutely certain of your target before you pull the trigger. 6. WEAR SHOOTING GLASSES AND HEARING PROTECTORS WHEN YOU SHOOT.
8. DON’T SHOOT AT A HARD SURFACE, OR AT WATER. Bullets can glance off many surfaces like rocks or the surface of water and travel in unpredictable directions with considerable velocity. 9. NEVER TRANSPORT A LOADED FIREARM. Firearms should always be unloaded before being placed in a vehicle. A suitable carrying case or scabbard should by used to carry an unloaded firearm to and from the shooting area. 10. AVOID ALCOHOLIC BEVERAGES WHEN SHOOTING. Don’t drink until the day’s shooting is over.

WHY NO WARRANTY CARD HAS BEEN PACKED WITH THIS NEW RUGER FIREARM The Magnuson-Moss Act (Public Law 93-637) does not require any seller or manufacturer of a consumer product to give a written warranty. It does provide that if a written warranty is given, it must be designated as “limited” or as “full” and sets minimum standards for a “full” warranty. Sturm, Ruger & Company, Inc.
