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
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.
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.
