Understanding The Sear In Your Firearm

What Is The Sear In A Firearm?

The sear is an integral component of a firearm’s trigger mechanism. It’s a tiny part that holds the hammer or striker in position before it releases to ignite a round in the chamber. It works by receiving the pressure from the finger on the trigger and then releasing the hammer or striker to strike the firing pin.

It’s a crucial component that ensures the firearm’s safety by keeping the hammer or striker in place until you’re ready to fire.

Here are a few things to keep in mind about the sear in your firearm:

  • The sear is a small metal piece responsible for releasing the hammer or striker.
  • It receives pressure from your finger on the trigger to release the hammer or striker.
  • It’s a crucial safety component that helps prevent accidental discharges.

Reassembling Your Firearm And Testing The Sear

Cleaning a firearm sear is an essential part of gun maintenance. Once you have disassembled it and cleaned the parts, you need to be sure you reassemble it correctly and test the sear to ensure it’s functioning correctly. Here are the steps you should follow to properly reassemble your firearm and test the sear:

Putting The Firearm Back Together

  • Start by reassembling the sear into the frame.
  • Align the sear pin with the holes in the frame, positioning it so it fits securely without binding or sticking.
  • Insert the hammer strut, and compress the mainspring to align it with the strut.
  • Replace the mainspring housing and push the lower pin through the frame to secure it, then install the grip panels or stock for your firearm.
  • Exercise caution and care while putting the firearm parts together.

How To Test The Sear For Proper Function

  • After assembling your firearm, check the sear’s functionality to ensure it has been correctly reassembled.
  • With the firearm unloaded, engage the safety and pull the trigger. The trigger should be unable to release the hammer. If it releases the hammer, the sear has not been correctly reassembled.
  • With the safety disengaged, pull the trigger again. The hammer should fall freely, allowing the firearm to discharge.
  • If the sear does not function as expected, disassemble the firearm and carefully examine the sear components for wear or damage. Replace any damaged parts before attempting to reassemble the firearm.

Troubleshooting Issues With The Sear After Cleaning

  • If the sear does not function properly after cleaning it, carefully disassemble the firearm again and inspect the sear components for wear, damage, or incorrect alignment.
  • Any worn, damaged, or misaligned parts should be replaced or repaired by a professional gunsmith before attempting to reassemble the firearm.
  • Never force a damaged or worn sear back into place, as it can cause further damage to the firearm.
  • Testing the firearm for proper function is essential after cleaning or repairing the sear, as malfunctioning parts can create safety hazards for the user.
