Considerations & Trade-offs

  • Designed for Glock Gen 3 and Gen 4 9mm models only, so fitment is limited to the listed G17, G19, and G34 handguns.
  • The compensator is intended to add control and support faster follow-up shots, but it also adds a muzzle device that changes the handgun’s original setup.
  • Installation requires the included set screws, so it is not a drop-in accessory with no setup.
  • Available in black or gold finishes, which may matter if you want the compensator to match the rest of the build.
