This titanium-plated firing pin for Glock Gen 1-4 drops into 9mm, .40 S&W and .380 slides. It is machined from 4041 steel instead of the metal-injection-molded (MIM) pin that ships from the factory, so it is a straightforward durability upgrade for a carry or range gun.
The titanium plating adds surface hardness and helps the pin shed carbon and fouling, which keeps it moving freely in the firing pin channel between cleanings.
Features:
Compatibility: Gen 1-4 only. This pin does not fit the Glock 43, and it is not intended for Gen 5 slides. Reuse your existing firing pin spring, spacer sleeve and spring cups.
After installing, reassemble the slide and confirm the firing pin moves freely and returns under spring tension before you fire it. Function-check the trigger reset, then test-fire a few rounds at the range before carrying.
