Glock Gen 4 Thread Protector Features The Glock Gen 4 Thread Protector is a factory part made to thread directly onto the exposed muzzle of a G23 Gen 4 barrel shielding the threads from dirt moisture and incidental damage. Keeping the threads capped when no muzzle device is attached helps preserve a clean precise fit the next time a suppressor or compensator is installed. As a genuine Glock accessory it is built to the exact thread specification of the factory threaded barrel it is designed for. This straightforward design requires no tools beyond simple hand-tightening to install or remove. Finished in black to match the factory barrel and slide the thread protector keeps a low profile while the pistol is holstered or stored. It ships as a single piece packaged ready to install making it an easy add for an owner who already has a threaded G23 Gen 4 barrel. Carrying the Glock name ensures proper fit and reliable function without the guesswork of an aftermarket part. The Glock Gen 4 Thread Protector is for sale at GrabAGun for shooters who want OEM-correct protection for their threaded muzzle.
