WEAR EYE PROTECTION AT ALL TIMES. NEVER DISASSEMBLE BEYOND WHA T IS EXPLAINED AND SHOWN IN THIS OWNER'S MANUAL.

Disassembling the action can be done in the field, but remember there are small parts involved, some of which are under spring tension. First, be certain there are no shells in the magazine or chamber.

Removal of the Barrel—

1. Open the action and make sure the gun is unloaded.

2. Close the action and place the safety in the "on safe" position.

3. Unscrew and remove the magazine cap. Remember, always keep the end of the magazine pointed in a safe direction.

4. Slide the barrel forward, withdrawing the barrel from the receiver and disengaging the barrel bracket from the front end of the magazine.

5. Immediately screw the magazine cap back onto the magazine.

Removal of the Triqqer Quard Qroup From the Receiver —

Removing the trigger guard group is another necessary procedure in performing thorough maintenance of your shotgun. It is easy to do, and removing it allows you to perform cleaning and maintenance whenever and wherever required. With both the trigger guard group and bolt assembly removed, it is easy to wipe out any debris or moisture that sometimes accumulates in the receiver. The trigger guard group should be removed before you attempt to remove the bolt assembly.

1. Make sure the gun is completely unloaded as explained previously in this owner's manual.

2. Cycle the action by sliding the forearm rearward and then forward. This puts the hammer in the cocked position. Place the safety in the "on safe" position.

3. If the barrel assembly has been removed, always be sure to replace the magazine cap on the end of the magazine tube to prevent accidental disengagement of the magazine spring retainer.

4. Place your gun with the trigger guard facing up on a suitable surface that will protect the receiver finish and stock.

5. Remove the trigger guard pin by pushing it out from the LEFT side of the receiver, the side opposite the ejection port. Any sturdy pushing tool that is smaller in diameter than the pin and will not mar the finish is acceptable. Make sure you can maintain a good grip on the pushing tool and on your shotgun while you push.

6. Push the pin through sufficiently until it can be grasped with your fingers. Pull it the rest of the way out. If it cannot be removed with fingers, make sure your pushing tool or punch has a diameter small enough so that it will push the pin completely through without the tool damaging the hole.

7. With the pin removed, lift the trigger guard group out of the receiver by lifting upward and pulling rearward (Figure 13).

Disassembly of the Slide and Breech Bolt (12 qauqe only) —

1. Remove the barrel and trigger guard group as explained earlier, but do not replace the magazine cap.

2. With the action slide arms still attached to the slide arm bridge, simultaneously slide both assemblies forward and out of the front of the receiver. Note that as the breech bolt assembly passes by the ejection port, there may be some resistance from the ejector spring. Carefully work it past the resistance.

Disassembly of the Slide and Breech Bolt (20 qauqe only) —

This procedure is necessary because the bolt will not extract out through the front of the receiver as it does on the 12 gauge model.

1. Remove the barrel and trigger guard group as explained earlier, but do not replace the magazine cap.

2. You must disengage the slide arms from the slide arm bridge. Remove the slide arms through the front of the receiver. Remove the bolt slide assembly through the trigger guard group opening.

Removal of the Firinq Pin —

Begin with the breech bolt assembly removed from the gun.

1. Grasp the breech bolt assembly, bottom side up (flat side), and push the rear of the firing pin forward with your forefinger. While holding the firing pin in this position, take your other hand and tilt the front end of the slide arm bridge and move it slightly forward. Lift up on the slide arm bridge and disengage the curved tongue on the slide arm bridge from the groove in the firing pin. This will detach the slide arm bridge from the breech bolt slide.

2. The firing pin is under spring tension and will snap out the rear of the breech bolt when your forefinger releases it. Control the pin as you remove the firing pin and spring.

For cleaning purposes no further dismantling is necessary or recommended. Do not disassemble your Model 1300 further than shown in Figure 11 shown on page 20. Doing so may void your warranty. For repairs that require further disassembly contact a Winchester Firearms Authorized Service Center or a qualified gunsmith as explained under "Parts, Service, Repair and Questions" on page 27.

Reassembly of the Firinq Pin, Breech Bolt and Slide (12 qauqe only) —

1. Reinstall the firing pin spring over the firing pin. Either end of the spring can go on first.

2. Insert the firing pin/spring assembly into the rear opening of the bolt slide, pin end first.

3. To reinstall the bolt assembly on the slide arm bridge, push or compress the "knob end" of the firing pin sufficiently into the hole in the bolt slide so that the large space between the grooved "knob" and the flange

on the firing pin is centered in the round hole in the bolt slide.

4. Place the curved tongue, located on the slide arm bridge, into the space between the knob and flange and slowly release pressure on the end of the firing pin. Let the flange on the pin pull the tongue toward the rear of the bolt assembly. This should hold the breech bolt assembly and the slide arm bridge together during further assembly.

5. With the firing pin and breech bolt now assembled, engage the slide arm bridge into the matching cuts on the slide arms (Figure 14).

6. Hold the slide arms and bolt/slide arm bridge assemblies together. Start the forearm assembly onto the magazine tube.

Carefully guide the bolt assembly — on the slide arms — into the receiver.

7. Remove the magazine cap and carefully guide the slide arms and bolt/slide arm bridge assemblies into the front of the receiver. As the assemblies enter the receiver, slide them fully rearward (Figure 15).

Reassembly of the Firinq Pin, Breech Bolt and

1. Reinstall the firing pin spring over the firing pin. Either end can go on first.

2. Insert the firing pin and spring into the rear opening of the bolt slide, pin end first.

3. To reinstall the bolt assembly on the slide arm bridge push or compress the "knob end" of the firing pin sufficiently into the hole in the bolt slide so that the large space between the grooved "knob" and the flange on the firing pin is centered in the round hole in the bolt slide.

4. Place the curved tongue, located on the slide arm bridge, into the space between the knob and flange and slowly release pressure on the end of the firing pin. Let the flange on the pin pull the tongue toward the rear of the bolt assembly. This should hold the breech bolt assembly and the slide arm bridge together during further assembly.

5. With the trigger guard group removed, insert the bolt assembly through the trigger guard opening up into the receiver. The front face and extractor of the bolt assembly should be facing the barrel or front of the shotgun. The slide arm bridge should be facing down toward the trigger guard group opening.

6. While holding the bolt assembly in place, insert the slide arm bars into the breech and connect them to the slide arm bridge.

Reinstallation of the Triqqer Quard Qroup —

Be careful when reinstalling the trigger guard group. Never force parts into position. The bolt assembly, slide arms and barrel should be attached before installing the trigger guard group. The hammer should be in the cocked position and the safety in the "on safe" position. Carefully insert the trigger guard group into place. It may be necessary to slide the forearm into different positions until the trigger guard group fits flush into the receiver. When properly installed it will fit easily and the pin will slide in without excessive force. Installing the bolt assembly after the trigger guard group is installed should not be attempted. Consequently, make sure you have already installed the bolt assembly before installing the trigger guard group.

It is not necessary that the barrel already be attached to install the trigger group. Install the trigger group as follows:

1. Turn your shotgun over with the open bottom of the receiver facing upward. Hold the trigger guard group at an angle to the receiver (about 45 degrees) and then engage the front tabs on the trigger guard group with the corresponding slots in the magazine throat at the forward end of receiver opening as shown earlier in Figure 13.

2. Rotate the trigger guard group towards and into the receiver opening, until it is parallel with the receiver.

3. Align the trigger guard group with the hole in the receiver and install the trigger guard pin from the RIGHT side of the receiver (ejection port side) until it is flush with both sides of the receiver. The pin should pass through easily with little force. If significant resistance is felt, remove the trigger group and repeat step one.

Your Model 1300 shotgun is now fully assembled. Immediately confirm that the safety is in the "on safe" position. Take time to wipe down and clean all external surfaces as explained under "Cleaning and Maintenance Suggestions" below.

cleaning and maintenance suqqestions

Your Model 1300 will function better and more reliably over a longer period of time if it is properly maintained and kept clean.

BEFORE PERFORMING ANY CLEANING PROCEDURES, AL WA YS MAKE CERTAIN THERE ARE NO SHELLS IN THE CHAMBER, MAGAZINE OR ACTION/FEED AREAS.

You should clean your Model 1300 after every day of shooting and more often if it becomes excessively dirty.

A minimum cleaning includes wiping down the action and oiling key parts. Most regular maintenance will also include cleaning the barrel. If you encounter a function problem (tight action when working the forearm) be sure to give your gun a thorough cleaning to see if it solves the problem before seeking the services of our service facility or a competent gunsmith. To clean your firearm, adhere to the following general guidelines.

Cleaninq Procedures —

ALWAYS PLACE THE SAFETY IN THE "ON SAFE" POSITION BEFORE BEGINNING ANY CLEANING PROCEDURE AND BE CERTAIN YOUR GUN'S CHAMBER AND MAGAZINE ARE UNLOADED.

ALWAYS WEAR PROTECTIVE SAFETY GLASSES DURING ALL CLEANING PROCEDURES. KEEP AMMUNITION AWAY FROM THE CLEANING AREA. DO NOT TEST THE FUNCTION OF YOUR FIREARM WITH LIVE AMMUNITION.

1. Use a cleaning rod with a tip and patch suitable for the size of your Model 1300's bore. Make sure the patch is large enough for a snug fit in the bore. Insert the rod and patch into the barrel at the receiver end and run it back and forth several times.

2. Inspect the chamber and bore for lead and powder fouling. A normal amount of powder residue can be expected and is not serious. It can usually be removed by repeating step one, using a patch saturated with solvent. If fouling should become heavy, it can be removed with a brass bore brush. Dip or spray the brush with solvent and scrub the chamber and bore until the fouling is removed. To prevent brass bristles from breaking off, the brush should be pushed completely through the bore before being withdrawn.

3. After fouling has been removed the bore should be wiped dry. Then pass a lightly-oiled patch through the bore for preservation. A fine, light gun oil is recommended.

4- Wipe all exposed metal surfaces of the receiver, forearm and barrels with a clean rag. Finger marks should be removed because they provide a place where moisture can accumulate. Any dried oil in the receiver area should also be removed.

5. Lightly oil your gun at the points described under "Initial Cleaning/Oiling" found on page 5. Ordinary good judgment will, of course, indicate that the metal of the gun should receive a light film of oil any time the gun has been exposed to weather or handling. This is very important and must be done with every firearm — even stainless steel models. Remember, the polished, finely fitted surfaces of the receiver and action mechanisms must always have a thin film of oil. Make sure that the surfaces of the locking pin system and the hinge components are especially clean and lightly oiled with a high-quality gun oil.

6. INSPECT THE BARREL AND CHAMBER. MAKE CERTAIN THAT NO PATCHES HA IIE BEEN INADVERTENTL Y LEFT IN THEM. REMOVE ANY THAT REMAIN.

7. Wipe all wood surfaces with a soft cloth.

8. When transporting only, store your Model 1300 in a quality protective case to prevent scratches and dents. Store in a dry place to prevent corrosion. Store away from children.

MAKE SURE YOUR SHOTGUN IS UNLOADED AND ALWAYS STORE AMMUNITION SEPARATELY.

DO NOT TAKE YOUR GUN'S ACTION OR TRIGGER GROUP APART BEYOND WHAT IS EXPLAINED IN THIS MANUAL.

Your Model 1300 is a specialized, finely-fitted mechanism. You may permanently mar it by attempting to disassemble the inner mechanism assemblies. If further disassembly for service or cleaning is required, take your gun to a Winchester Firearms Authorized Service Center or a qualified gunsmith as explained under "Parts, Service, Repair and Questions" on page 27.

Other Cleaninq Suqqestions —

• Never pour large quantities of oil into the receiver or other parts. It can drain down to the wood and soften it, causing permanent damage and loosening of the stock.

• After extended periods of heavy use, your gun should be taken to a qualified gunsmith to have the action disassembled for professional cleaning and lubrication.

Cleaninq Parts With Special Finishes —

Be especially careful when cleaning guns with camouflage, Dura-Touchf' Armor Coating and other special finishes.

Always prevent these surfaces from coming in contact with cleaning solvents, barrel scrubbers and other strong chemicals. It is preferable to clean these surfaces with a light gun oil containing no solvents or with a damp cloth and mild dish soap (be sure to keep water out of the action). When cleaning your firearm's bore and action, protect the external finishes from any contact with chemicals used. Also, avoid any contact between external finishes and other strong chemicals like those found in DEET-containing insect repellents, sunscreens, etc. Damage to camouflage, Dura-Touch and other finishes caused by chemicals is irreversible and unrepairable.
