GLOCK Maintenance 

Proper cleaning of your Glock is the best thing you can do to keep the gun looking good and functioning well for decades to come. Luckily, the intelligent design of Glocks makes cleaning a relatively simple and, for some, even pleasant experience.

Here at King Glock we choose to use Break Free's Powder Blast Solvent and Break Free CLP Lubricating Oil. Although you are free to use any products you choose, we do discourage the use of any solvent containing ammonia. The reason is due to the fact that ammonia dissolves copper, which is used in the nickel plating process GLOCK uses on its internal parts. Any imperfections, scratches or pits in the nickel will allow any ammonia solvent to dissolve the copper base layer and cause premature brittleness and flaking.

Break Free CLP
When the United States Military issued PD-48, a purchase description of properties for a single, multi-purpose product to maintain their weaponry, it became known as the "impossible specification" because of its severe requirements. The first product to meet the challenge - Break-Free CLP. Break-Free's flagship product, CLP is a unique formulation of synthetic oils and individual proprietary ingredients which synergize in combination to do three important tasks simultaneously: Effectively Clean, Lubricate and Protect metal. Break-Free CLP is now recognized around the world as the standard by which maximum metal performance and protection is ensured.

Glock Lubrication


To properly lubricate your Glock pistol, after it has been thoroughly cleaned and dried, use a clean patch that has been slightly dampened with a quality gun oil. Wipe the barrel, the inside of the slide where the barrel hood rides against the slide and wipe the barrel lug at the bottom of the barrel. Apply one drop to each of the slide rail grooves (once the slide is moved on the receiver, the oil will be distributed to each of the slide rails). The most important drop of oil is placed where the trigger bar and connector meet. Failure to properly lubricate the junction of the trigger bar and connector can lead to premature wear and a very heavy trigger pull.

Do not over-lubricate your Glock. Glock pistols are designed to operate properly with only small amounts of lubrication. Over-lubrication can cause the gun to collect large amounts of burnt and unburnt powder, brass shavings, dirt, lint and other foreign matter that can affect the proper functioning of your gun.


Do not put oil inside the firing pin channel, around the extractor, on the breech face, any where near the barrel chamber or feed ramp, nor in the magazine. These areas should be kept clean and free from lubricant. Lubricant in these areas can cause contamination to primers and result in a failure to fire.

Dry Firing

Glock pistols can be dry fired without damage to the pistol. Do not pull back the lug of the firing pin and let it snap forward when the slide is removed from the receiver. Damage to the firing pin and firing pin safety can occur.
