Why Replace Your Firing Pin Safety Spring?

Over time, the firing pin safety spring can lose tension due to repeated cycling, exposure to moisture, or mechanical shock. A weakened spring may cause:

  • Inconsistent safety engagement
  • Delayed or unreliable trigger reset
  • Increased risk of accidental discharge

Replacing the spring with the genuine GLOCK OEM part restores factory‑level performance, giving you confidence in every shot.

Installation Guide (Quick Overview)

  1. Ensure the firearm is unloaded and the magazine is removed.
  2. Disassemble the slide according to the Glock manual – remove the recoil spring assembly.
  3. Locate the existing firing pin safety spring on the firing pin assembly.
  4. Using a small punch or the provided removal tool, carefully depress the old spring and remove it.
  5. Insert the new GLOCK OEM Firing Pin Safety Spring (SP00091) ensuring it sits flush.
  6. Reassemble the slide, perform a function check, and verify proper safety operation.
