How to Clean a Firearm'S Firing Pin Stop?


Understanding The Firing Pin Stop And Its Importance

Definition And Function Of A Firing Pin Stop

Before we dive into cleaning the firing pin stop, let’s first understand what it is and what it does.

  • The firing pin stop is a component of a firearm’s slide that is responsible for stopping the firing pin from moving too far forward after hitting the primer.
  • Its main function is to prevent the firing pin from piercing the primer and causing catastrophic damage to the weapon.
  • It is typically made of hardened steel and sits behind the firing pin in the slide assembly, held in place by the firing pin stop plate.

Why Cleaning The Firing Pin Stop Is Critical

Cleaning the firing pin stop is a crucial maintenance task that should not be overlooked. Here’s why:

  • A dirty or fouled firing pin stop can cause malfunctions or misfires by preventing the firing pin from striking the primer with sufficient force or at the correct angle.
  • Over time, carbon, dirt, and debris can build up around the firing pin stop, increasing its friction and preventing it from moving smoothly, which can lead to failures to eject or extract rounds properly.
  • Neglecting to clean the firing pin stop can also contribute to accelerated wear and tear on the weapon, reducing its lifespan and reliability.

Common Issues Caused By A Dirty Firing Pin Stop

Now that we know why cleaning the firing pin stop is important, let’s take a look at some typical issues that can result from a dirty or worn firing pin stop:

  • Light primer strikes: A dirty firing pin stop can interfere with the firing pin’s ability to strike the primer with enough force, resulting in light primer strikes and misfires.
  • Failures to eject: A fouled firing pin stop can lead to extraction failures and stovepipes, where a spent cartridge fails to eject or gets stuck during the ejection process.
  • Reduced accuracy: A dirty firing pin stop can affect the firearm’s accuracy by causing the firing pin to strike the primer at an incorrect angle, resulting in inconsistent bullet velocities and trajectories.

Safety Precautions To Take Before You Clean

Before you start cleaning the firing pin stop, there are several safety precautions to keep in mind:

  • Always make sure the firearm is unloaded and the magazine is removed before cleaning.
  • Keep the muzzle pointed in a safe direction and always wear eye and ear protection.
  • Follow the manufacturer’s instructions for disassembling and cleaning the slide assembly, and use only recommended cleaning products and tools.
  • Do not force anything or use excessive pressure when cleaning to avoid damaging the firing pin stop or other components of the firearm.

Preparing For Firing Pin Stop Cleaning

Cleaning your firearm’s firing pin stop is an essential part of firearm maintenance that should never be overlooked. The firing pin stop is responsible for holding the firing pin in place and aligning it correctly with the primer, ensuring your firearm fires accurately and safely.

We will detail the necessary steps required to clean your firearm’s firing pin stop.

Step 4 – Inspecting The Firing Pin Stop And Firing Pin

Inspecting the firing pin stop and firing pin is also important. You should look for any cracks, chips, or burrs on the firing pin stop and the firing pin. If you find any defects or flaws, replace them immediately.

Step 5 – Reassembling Your Firearm

After you’ve inspected and cleaned the firing pin stop and firing pin, it’s time to reassemble your firearm. Here’s how:

  • Slide the barrel back onto the slide and push the barrel lugs into place.
  • Reattach the recoil spring and guide rod.
  • Align the slide’s rails with the frame, and fit the slide onto the frame.
  • Push the slide until it clicks back into place.
  • Reinsert the magazine.

Step 6 – Testing Your Firearm

Now that you’ve reassembled your firearm, it’s important to test it before using it. You should test the firearm by:
