Glock lubrication: where to oil, what to use and how much

Glock's own manual lists a handful of lubrication points and says to use a drop at each, and most problems traced to lubrication come from ignoring the second half of that sentence. A Glock runs on very little oil, in the right places, and it runs badly on a lot of oil in the wrong ones. This guide gives the points, the products, the amounts, and the adjustments for weather and storage.

The points

With the pistol field stripped and wiped clean, one drop of oil at each of these, spread with a fingertip:

The slide rails: the four rail cuts inside the slide, front and rear, where they ride the frame rails.
The barrel hood: the top of the squared block behind the chamber, where it locks into the slide.
The outside of the barrel: a light film where the barrel rubs the inside of the slide near the muzzle, and on the lug where it meets the locking block.
The connector: one drop on the angled face at the rear of the trigger housing, visible from above with the slide off, where the trigger bar's tab rides.
The trigger bar: a light touch where it contacts the connector and where the ramp meets the firing pin safety.

What stays dry

The striker channel: oil here collects residue and thickens in the cold, and light strikes follow. Clean it with a dry patch and leave it dry.
The firing pin safety plunger: a dry plunger moves freely; an oiled one gums.
The magazines: inside and out. Oil holds grit and swells followers.
The extractor and its channel: a wipe, not a drop; oil there attracts carbon.
The polymer frame: nothing needs oil except the rails.

How much

A drop is a drop. Spread it with a fingertip so the surface looks wet, not so it drips. The whole pistol takes five or six drops. More oil does not make the pistol more reliable; it makes it a magnet for dust, lint and unburned powder, and in a carry gun it soaks into clothing and holsters. A pistol that leaves an oil ring on a table has too much.

Oil, grease or CLP

A light gun oil is the right product for a Glock in every climate; the manual specifies oil. Greases stay put on rails and suit a range gun in hot weather, but they thicken in the cold and collect grit, so keep them off a carry gun and out of a winter gun. CLP products clean, lubricate and protect in one and are fine on the rails and barrel; use them lightly and keep them away from the striker channel. Dry lubricants and coatings marketed as needing no oil work until they wear, which they do quickly on the rails; treat them as a supplement.

Cold weather

Below freezing, thick oils and greases slow the slide and the striker. Use a thin oil rated for cold, use less of it, and make sure the striker channel is dry. A pistol brought from a cold car into a warm house sweats; wipe it dry before it goes back in the holster.

Hot and dusty weather

Heat thins oil and it runs off the rails; dust sticks to whatever is left. Oil more often and less at a time, wipe the outside of the pistol dry, and keep the striker channel and magazines clean. A grease on the rails holds up better in heat on a range gun that is not carried.

Wet and salt

After rain, sweat or salt air, field strip, dry every part, and put a light film of oil on every steel surface including the outside of the slide and the barrel, not just the points above; then wipe the excess off before reassembly. A silicone cloth wipe on the outside keeps rust off a carried pistol between cleanings. The striker channel still stays dry.

Storage

A stored pistol gets the same drops plus a light film on the outside of the slide and barrel, a desiccant in the safe, and a check every few months. Before it goes back into service, field strip, wipe, run a dry patch through the channel and re-oil the points; oil that has sat for a year has usually migrated or dried.

Signs of too much and too little

Too much: oil visible on the outside, lint stuck to the frame, grit in the rails, light strikes from a wet striker channel, and a holster with oil stains. Too little: a slide that feels gritty when racked, bright wear lines on the rails and the barrel hood, and a pistol that runs but feels rough. The right amount is a slide that racks smoothly and a pistol that looks dry.

Aftermarket parts and lubrication

A pistol with an aftermarket trigger, a stainless or coated barrel or a threaded barrel with a compensator gets the same drops in the same places. Stainless barrels want a little more oil on the hood and lug, since they gall against a steel slide more readily than a nitrided factory barrel. A compensator stays dry; oil in its ports bakes into carbon. Polished trigger parts are lubricated lightly at the same points as factory parts, not flooded.

A five-minute routine

Unload, check twice, field strip.
Wipe everything dry; dry patch the striker channel if the striker is out.
One drop at each point above, spread thin.
Reassemble and rack the slide five times.
Wipe the outside.

Fit it into the maintenance schedule, and see which springs and parts wear regardless of oil in the parts cross-reference. Browse gun oil and cleaning gear; it ships to your door.
