Brownells 75th Anniversary - A Shooting Heritage

Reduced Recoil with an OEM Barrel

The Strike Industries G4 SlideComp is designed to allow Glock pistol owners to reduce the recoil impulse on their handguns without having to add a threaded barrel or otherwise permanently alter their handgun.

The Strike Industries G4 SlideComp works by mounting a compensator to the steel slide of a Glock pistol without the need for a gunsmith to make permanent changes to the gun. The design also matches the profile of the slide, allowing for compatibility with open-bottom holsters.

  • Features precise CNC machining
  • Includes Manganese-phosphate finish
  • Comes with installation screws, allen wrench and G17 guide rod and spring
  • Compatible with the company's SI-GUM

The Strike Industries G4 SlideComp can be used on Glock Gen 4 G17, G19, G22, G23, G31 and G32 pistol models.
