Introduction These instructions will show how to safely and effectively clean your Glock firearm. By following these step by step instructions, you will have a clean weapon that will optimize the accuracy and action of the shooting experience. It is very important that the firearm is unloaded and ammo is properly stored in another location. Having ammo away from the firearm will guarantee that there will be no accidental discharge. Follow these steps each time you clean your gun and it will prolong its life and accuracy. It only takes a few minutes to clean your gun, and these few minutes will extend the life of your gun for many years.

*** Safety Notice: failure to follow steps 1 and 2 could lead to accidental discharge and possible death. Firearms are extremely dangerous and should be handled only by those trained to use them.

Step #1 – IMPORTANT – Remove clip and ammo from gun. I recommend that you put the clip and any ammo in another location to completely avoid an accidental firing of the weapon. Also remove any accessories such as a light or laser from the front slide rail.

Step #2 – IMPORTANT – Check to be sure that there are no bullets in the chamber.

Step #3 – Locate the slide breakdown release switch located on both sides of the firearm. (Figure A) Figure A

Step #4 – Pull the slide back slightly with the right hand and using the thumb and forefinger of the left hand, press both sides of the slide release down (Figure B). This will allow the slide to be pushed forward as shown in Figure C and removed in Figure D. Figure B

Step #5 – Remove the slide spring by holding the slide as shown below. Depress the spring with your thumb. CAUTION: The spring is under strong compression and can release with harmful force. Use your hand as shown below to shield the spring from going airborne.

Step #6 – Removal of the spring shown in Figure E will allow the barrel to be removed shown in figures F and G. Now there are 4 pcs. shown in Figure H – the slide, the barrel, the spring, and the grip/trigger frame. Figure E

Step #7 - Apply a couple drops of oil to the .45 caliber brush and insert into the barrel.

Step #8 – Insert brush into the end of the barrel and push all the way through as seen in the following three figures. It is important to push all the way through the barrel to remover any debris that may be in barrel. Repeat this several times or until the barrel is clean of debris.

Step #9 – Using a clean patch, plunge the rod and patch through the barrel all the way through as seen below. Do this several times until the barrel is shiny and the patch is free from black debris. (Use a new clean patch after two or three plunges.)

Step #10 - Now that the gun is clean, apply a very small amount of gun oil to the barrel and wipe clean. Also apply a small drop of oil to the slide rails and grip as shown below. Reassemble the firearm by following steps 4 thru 6 in reverse order. OIL Slide




*** TROUBLE SHOOTING *** If you have any problems in the disassembly or reassembly of your firearm, do not force parts together. The pieces of your gun are precision made and should go together with ease. The only force needed in this process is the removal and reassembly of the spring. Please refer to a qualified gunsmith if you have any questions or concerns. Improper assembly could cause costly repairs, serious injury, and even death.
