Glock cleaning and maintenance schedule

A Glock will run dirty longer than almost any pistol, which is exactly why owners let it go too long. Cleaning is not about making it shine; it is about seeing the parts before they fail and keeping the few places that need oil oiled and the places that must stay dry dry. This guide gives a schedule by use, the steps for each level of cleaning, the tools, and the mistakes that cause more problems than dirt.

The schedule

After every range session: field strip, wipe, brush the bore, oil the five points, inspect.
Monthly for a carry pistol, even unfired: field strip, wipe lint and sweat from the slide, frame and holster, re-oil the rails, check the magazine.
Every 1,000 rounds or six months: the same plus a dry patch through the striker channel with the striker out, and a look at the extractor and springs.
Yearly or every 5,000 rounds: detail strip, clean every part, replace the recoil spring and any spring that shows wear.
After rain, sweat, salt or a fall in the dirt: field strip and dry the same day.

After a range session

Unload, check the chamber twice, and field strip into slide, barrel, recoil assembly and frame. Run a brass or nylon bore brush with solvent through the barrel from the chamber end, follow with dry patches until they come out clean, and wipe the outside of the barrel, the hood and the lug. Wipe the slide rails, the breech face and the inside of the slide with a rag and a nylon brush; do not flood the slide with solvent, which runs into the striker channel. Wipe the frame rails and brush around the locking block and trigger bar. Wipe the recoil assembly. Reassemble, oil the points in the lubrication guide, and cycle the slide a few times.

The carry-gun wipe

A carried Glock collects lint in the magazine well, sweat on the slide and dust in the holster, and none of it stops the pistol until a lot of it does. Once a month, field strip, wipe everything with a dry cloth, blow the lint out of the frame and the holster, put a fresh drop of oil on the rails and reassemble. Check that the magazine drops free and the rounds are not set back in the case from repeated chambering; shoot the chambered round at the next range trip rather than chambering it again.

The striker channel

With the striker assembly out of the slide, run a dry patch on a rod through the channel from the rear until it comes out clean. Never oil the channel: oil collects powder residue and, in cold weather, thickens enough to slow the striker and cause light strikes. A clean, dry channel is the single most important thing in this guide for reliability.

The yearly detail strip

Take the slide down to the striker, extractor and plunger, and the frame down to the trigger housing, locking block and slide stop. Clean every part dry. Replace the recoil spring assembly, and replace the trigger spring, slide lock spring and magazine springs if they are more than a few years old. Inspect the extractor claw, the striker tip, the cruciform on the trigger bar and the locking block face for wear, and the frame rails for cracks. Reassemble, oil, and run the function checks before live fire. The parts cross-reference tells you which replacement fits.

Magazines

Take the floorplate off, wipe the inside of the body, the spring and the follower dry, and reassemble without oil. Clean range magazines after dusty days and carry magazines every few months. Number them so a failing one can be retired.

Tools and supplies

A bore brush and rod or a pull-through in the right caliber, patches, a nylon brush, a bore solvent, a light gun oil, a rag and a cleaning mat. A 3/32 inch punch for the detail strip. A can of compressed air for lint. Skip the aerosol degreasers on a polymer frame and the aggressive solvents that attack finishes; a Glock needs mild products and a little time.

Mistakes to avoid

Oil in the striker channel or the magazines.
Too much oil anywhere: a drop, not a film. Oil attracts grit.
Solvent left in the slide: it runs into the channel.
Brushing from the muzzle: it wears the crown. Brush from the chamber.
Prying the cover plate with a screwdriver: press the sleeve with a punch.
Never checking the springs: they wear quietly and fail at the range.

The function check

After any cleaning that goes past a field strip, and before live fire, run the checks with the pistol confirmed empty. Rack the slide and confirm it locks back on an empty magazine and drops when the stop is pressed. Pull the trigger and confirm the striker releases, hold the trigger back while racking, and confirm it resets with a click when released. Push the firing pin safety plunger and confirm the striker cannot move forward until the trigger presses it. A pistol that fails any check goes back on the bench, not in the holster.

Storage

Store the pistol clean and lightly oiled in a lockbox or safe with a desiccant, magazines loaded, ammunition in a second container. A pistol stored for months in a leather holster picks up moisture from the leather; take it out. Cycle the stored ammunition through the range once a year. The ammunition guide covers what to store and what to shoot. Browse cleaning gear and replacement springs; they ship to your door.
