GENERAL RULES

 

Before we dive into the particulars, a few general rules apply:

Read your owner’s manual! Cops being cops, I know most of you have never cracked this open! Do yourself a favor and read the manual that came with your gun for the manufacturer’s recommendations on how to disassemble, clean and reassemble your pistol. There’s some good stuff in there, honest.

Follow the safety rules! It’s essential to follow your agency’s firearms safety rules every time you handle your firearm. Before you attempt to disassemble and clean your firearm, you must safely unload/clear it in accordance with the process described by the manufacturer or your agency, and ensure that the ammunition remains separate from the gun (ideally, in another location) until you’ve made the conscious decision to load it again.

Protective measures. Wear safety goggles to protect your eyes, and disposable gloves to keep lead and chemical residue off your skin. Ensure the area you’re working in has adequate ventilation. Clean up your work area when you’re finished, then wash your hands and face with cold water and soap (cold water is better than hot, to keep your skin’s pores from opening up and increasing your exposure), to avoid getting any chemicals or residue in your eyes, nose, or mouth.

 

GET IT CLEAN

 

A variety of cleaning products, tools and methods are available. Our goal here is to discuss a simple method, using common resources, so if you have a different technique or favor a different product, please continue with it ‒ we’re not trying to talk you out of it.

Starting with your protective equipment in place, and a field-stripped firearm, do the following:

  1. Run a solvent-soaked patch through the chamber and bore of your barrel several times, coating the feed ramp, chamber and interior of the barrel evenly. Set the barrel aside to soak.
  2. Wipe the interior of your slide with a dry patch or rag, to get the big stuff off. Wet a toothbrush with a small amount of solvent, and scrub the interior surfaces, paying close attention to the breech face and slide rails. As you’re scrubbing, try to hold the slide muzzle end down to avoid having the solvent run into the interior of the striker channel, which we want to keep dry. Set the slide aside to soak for a while, muzzle end down, so that any solvent that made its way into the striker channel can drain out.
  3. Clean the frame of your pistol with a dry patch or rag. Get the carbon, dirt and other fouling off the exterior of the frame, the interior of the magazine well and the accessible interior of the gun. Wipe down the rails, trigger bar, ejector and connector area as well (refer to your manual to identify these parts if you don’t know what they are).
  4. Now that you’ve got the big stuff off the frame, go back through with a toothbrush and a clean patch or rag to get the nooks and crannies clean. You may need to put a little solvent on the brush or patch to get some of the fouling off these parts ‒ if so, make sure you wipe the surfaces clean afterward and don’t leave a bunch of solvent behind. If necessary, use an air hose or a can of compressed air to blow the solvent out of the areas where it may be hiding. The goal here is to get everything clean and dry.
  5. Wipe down your recoil spring assembly with a dry patch or rag. It shouldn’t need much attention ‒ just try to get it clean and dry. A dry toothbrush might help, too.
  6. Wipe down the exterior of your magazines with a dry patch or rag to get the carbon fouling and dirt off. Pay close attention to getting the follower and feed lips clean – a dry brush might be helpful here. If you’re concerned that water, sand, dirt or other debris got inside the magazine, then you’ll want to disassemble the magazine and clean it. That’s a good thing to do periodically anyhow, but you don’t have to disassemble your magazines for cleaning every time. Once again, your goal is to get your magazines clean and dry. Don’t lubricate them or leave any solvent behind to attract more dirt. Clean and dry.
  7. Let’s return to the slide. Scrub it a little more with your brush, then wipe everything down to get the interior and exterior clean and dry. To get the rails clean, push a dry patch down into the rail with your toothbrush or a non-marring tool (like a plastic pick, wooden toothpick, or the paper shaft of a Q-Tip) and wipe clean from end to end – you’ll probably need several passes to do this. Make sure the breech face is clean and smooth, with no raised fouling on the surface (like rings of carbon or primer sealant). If necessary, use a brass brush or a non-marring tool to scrub or scrape the breech face clean. Get a clean patch behind the extractor hook and remove any gunk that built up there. (It will be periodically necessary to disassemble the slide to clean the extractor properly, and the striker/channel as well ‒ talk to your department armorer about this.) Lastly, wipe down the exterior. Remove any gunk around the extractor pocket, and ensure that your sights are cleaned off, so you can see them properly.
  8. Time for the barrel again. Run that solvent-soaked patch through the bore several more times, then run a few dry patches through the bore to get the gunk out and get the bore mostly dry. Use a dry patch or rag to clean up the feed ramp, to make it clean and shiny (a toothbrush might help, if it’s really fouled). Put a bristle brush on the end of the cleaning rod and run it through the barrel, from the rear, about 5-10 times. Wet a patch with oil and swab the barrel to clear out any particulates, then follow up with dry patches through the barrel to remove any oil and suspended debris. Inspect the bore and chamber to ensure they are clean. If not, then repeat the process as required, until you get the results you want. Wipe down the exterior of the barrel with your rag, so that both interior and exterior are clean and dry.

 

Cleaning your firearm begins with safely field stripping your pistol. Refer to the owner’s manual and/or your department guidelines for instruction on how to do this.

When you’re scrubbing the slide, hold it with the muzzle end down to prevent extra solvent and debris from running into the internals of the slide. If solvent and oil collect inside they can turn into a gummy residue that will prevent your pistol from working properly.

LUBRICATE

 

When the parts are cleaned to your satisfaction, lubricate and reassemble your pistol. Be sparing with the oil, because you don’t need much to ensure proper function, and any excess will just attract dirt. Furthermore, excess oil will coagulate and turn into a sticky residue that might impair the reliability of your pistol.

  1. Place a small drop of oil on the top exterior of the barrel near the muzzle. With your finger, smear it around the outside circumference of the barrel to distribute it in a ring.
  2. Place a small drop of oil on the square shelf where the hood of the barrel locks up into the slide. Smear it around the top of the hood with your finger then insert the barrel into the slide. Smear the remaining oil on your finger onto the locking lug on the underside of the barrel, then install the recoil spring assembly.
  3. While the gun is still apart, perform the firing pin safety check. Depress and hold the firing pin safety plunger in the bottom of the slide with your thumb, and shake the slide back and forth ‒ you should hear the firing pin/striker freely moving back and forth in the slide.
  4. Place a small drop of oil on each of the four frame rails, then smear it around with your finger to coat the top, side, and underside of each rail.
  5. Place a small drop of oil where the trigger bar meets the connector.
  6. Install the slide on the frame, and rack it several times to distribute the oil on the rails, barrel, and barrel hood.
  7. Wipe down the exterior of the pistol with a clean rag, to clean up any excess oil.

Do the “tinkle test” to ensure your striker moves freely. Hold the firing pin safety plunger down, and shake the slide back and forth. You should hear and feel the striker moving around in its channel. If it doesn’t, you need to disassemble the slide and clean out the channel and striker components.

FUNCTION CHECK

Once the pistol is lubricated and assembled, perform a function check to ensure the system is working properly.

  1. Ensure the firearm and magazines are unloaded.
  2. Without a magazine in place, rack and release the slide to cock the striker. Aiming the unloaded pistol in a safe direction, pull and hold the trigger to the rear. You should hear and feel the striker slam forward when you pull the trigger.
  3. While holding the trigger to the rear, rack and release the slide to cock the striker again.
  4. Slowly release the trigger, and listen/feel for the trigger to reset.
  5. Insert an unloaded magazine into the pistol.
  6. Rack the slide to the rear. It should remain back with an unloaded magazine in place.
  7. Remove the magazine and set it aside.
  8. Tug and release the slide, or push the slide lock lever down, to send the slide forward into battery.
  9. Insert another unloaded magazine into the pistol. Repeat steps 6-8 as required, for all your unloaded magazines, to ensure all of them will lock the slide to the rear.
