Overview

Built for Glock Gen 3 and Gen 4 9mm handguns, this compensator is intended to help shooters gain more control and quicker follow-up shots. Its two-chamber design uses vertical ports and side vents, and it is offered in a black finish. It fits Glock G17, G19, and G34 models, and ships with the set screws needed for installation. For hunters and outdoorsmen who also rely on a defensive or range pistol, it offers a focused way to tailor recoil management without changing the handgun’s core setup.

Considerations & Trade-offs

  • Designed for Glock Gen 3 and Gen 4 9mm models only, so compatibility is limited to the listed G17, G19, and G34 platforms.
  • Installation requires the included set screws, which adds a setup step compared with a drop-in accessory.
  • The compensator is intended to add control and help with faster follow-up shots, but it also changes the muzzle profile of the handgun.
  • Finish options are limited to black or gold, so there is no broader color selection in the provided data.
