  • Available in black and gold finishes

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.
  • The compensator adds an extra muzzle device component, which may require installation and setup using the included set screws.
  • Its two-chamber, ported design is intended to change how the pistol behaves under recoil, so results will depend on the shooter and load used.
  • Available in black or gold finishes, but the product shown here is the black 1/2''x28 version, so finish and thread pattern should be matched carefully to the firearm.
