Strike Industries Mass Driver Comp for Gen 4 Glock Pistols


When you’re ready to step away from the crowd and lead, Strike Industries and Wing Tactical have the Glock Gen 4 Comp you need. The Strike Industries Mass Driver Comp for Generation 4 Glock pistols is an idea whose time has come.

The Problem with the Traditional Glock Gen 4 Comp

Isn’t that the baffles and ports aren’t doing their jobs. They really are doing the best they can to mitigate recoil and muzzle rise given the way they work. There’s only so much you can do to reroute gasses and have a positive impact. The problem is, those traditional compensators add to the reciprocating mass of the pistol when it’s fired. Since the mass of a Glock is relatively small, the addition of a compensator can add a significant percentage of additional reciprocating mass, and create even more perceived recoil and motion that negatively effects control. Strike Industries knows we can do better.

Forward Function

The Strike Industries Mass Driver Comp does it’s job to regulate the expulsion of gasses on firing, then instead of moving backward and up with the main mass of the firearm, it reacts on its own, counterbalancing against the motion of recoil. That forward counterbalance helps to flatten the reaction of the fired weapon.

Sleek Design

The Strike industries Mass Driver Comp appears as a seamless addition to the Gen 4 Glock when it’s at rest. It’s not bulky or awkward, and your Gen 4 Glock won’t fit any differently in the average holster than any other Glock with an equipped compensator. The pros at Strike Industries have done an awesome job with this one. This one brings cutting edge Performance and good looks in one.
