Glock Trigger Housing Pin Features The Glock Trigger Housing Pin is a polymer component built for Gen4 and Gen5 pistols without modular backstraps covering models such as the SF variants G30S G36 G40 Gen4 G19X G44 G45 and G45 MOS. This solid short pin is compatible across a wide range of calibers including 9mm 10mm .40 S&W .45 ACP .380 Auto and .357 SIG. The black polymer finish matches the factory components found throughout the trigger assembly on these pistols. As a direct factory replacement it restores proper fit and function when an original pin has worn or become damaged. A worn or damaged trigger housing pin can affect how securely the trigger housing is retained within the frame so replacing it with a genuine factory part is important for reliable function. Because this pin is built to Glock s own specifications it installs the same way the original did with no modification required. Owners and armorers maintaining a range of Gen4 and Gen5 pistols benefit from keeping this versatile pin on hand given its broad caliber and model compatibility. This small but important part helps keep multiple Glock models operating reliably across their service life.
