Disassembly and Field Stripping

When it comes to cleaning a Glock, the first step is disassembling the handgun and performing a field strip. This process involves separating the firearm’s main components, including the frame, slide, barrel, and recoil spring assembly. This section will provide you with step-by-step instructions on how to disassemble your Glock for cleaning properly.

Unload the Glock

Before starting, always ensure your Glock is unloaded to prevent accidental discharge. Remove the magazine and visually inspect the chamber to confirm that it’s clear of any rounds. Additionally, ensure your work area is free of ammunition for added safety.

Remove the Slide

To remove the slide, follow these simple steps:

  1. Ensure the unload process is complete.
  2. Pull the trigger to release the firing pin.
  3. Grasp the Glock firmly with one hand, while using the other hand to retract the slide slightly.
  4. While holding the slide back, pull down on both sides of the slide lock.
  5. Gently guide the slide forward, completely separating it from the frame.

Detach the Barrel and Recoil Spring Assembly

Once you remove the slide, it’s time to detach the barrel and recoil spring assembly.

  • Start by removing the recoil spring assembly: grip it at its base, compress it slightly, and lift it out of the slide. Set it aside.
  • To remove the barrel, lift the rear of the barrel away from the slide, then pull it out and away.

With your Glock now properly disassembled, you are ready to move on to the cleaning process. These steps should be performed carefully and methodically to ensure a safe and effective cleaning experience. By following these instructions, you’ll be well on your way to a clean and well-functioning firearm.

Cleaning Solvents

Cleaning solvents are crucial in removing fouling, debris, and residue from your Glock. Various gun-cleaning solvents are available, each designed to specifically target different types of buildup. Examples of solvents include bore cleaners, spray cleaners, and CLPs (cleaner, lubricant, protectant). Make sure to choose a solvent that is appropriate for your firearm and follow the manufacturer’s recommendations.

Cleaning Brushes

Brushes serve a vital role in scrubbing away stubborn grime and deposits. A toothbrush-like gun cleaning brush is often recommended for effectively cleaning the frame and slide of a Glock. Nylon, bronze, and steel brushes are the three main brush types, with nylon brushes being the gentlest and steel brushes being the most aggressive. When using brushes, select the right type based on the material of your gun and the level of fouling to prevent damage.


Cleaning patches are essential for wiping down surfaces and removing loosened debris during cleaning. They are available in various materials such as cotton, microfiber, and synthetic materials, which can be used in conjunction with a cleaning rod to clean the barrel thoroughly. Properly sized patches will ensure a snug fit and effective cleaning action.

Q-Tips and Tools

Q-tips and specialized tools help reach those small and tight areas that are difficult to access with patches and brushes. Using a Q-tip allows for precision when applying solvent and oil to specific spots or dislodging debris without causing any inadvertent damage. Tools like dental picks can also assist in scraping away stubborn fouling if needed.
