Glock 47738 9Mm Fits 17 Gen4 Black Steel

The Glock 47738 is a threaded 9mm barrel built for the Glock 17 Gen4, designed to let you run a compensator or suppressor while keeping your carry gun practical. It's machined from black steel and features 1/2x28 right-hand threading—the standard for most 9mm muzzle devices on the market. Whether you're looking to reduce recoil at the range, shoot suppressed, or just want the option to thread on a brake down the road, this barrel keeps your Gen4 17 relevant and modular.

Upgrading to a threaded barrel is one of the smartest moves for shooters who want flexibility. You're not locked into iron sights or a slide-mounted optic—you can add weight forward of the muzzle to manage recoil, or run it bare if you prefer. The barrel comes with a thread protector, so you can carry and shoot without worrying about damage to the threads or whatever you plan to thread on later.

Fit and function are straightforward: drop it into your Glock 17 Gen4 just like you would any OEM barrel. Black steel is durable and resists corrosion well enough for field use, and the compact dimensions mean you're not adding unnecessary length to a carry gun. This is the kind of accessory that pays for itself the moment you want to run a can or compensator.
