Questions & Answers
Will this compensator work with a glock 47 MOS? And will it work with a threaded barrel? Manufacturer Answer

For the MDCOMP it is advised to use the listed compatible OEM Glock 17/19 slides or our Lite Slide. We recommend use with non-threaded barrels if possible but yes, the Mass Driver Comp is compatible with most GLOCKâ„¢ aftermarket threaded barrels. We've tested with majority of the popular brands on the market such as: AlphaWolf, Battle Arms Development, Bear Creek Arsenal, Brownells, CMC Triggers, Faxon Firearms, Fortis Manufacturing, Grey Ghost Precision, Killer Innovations, LANTAC, Lone Wolf Distributors, Next Level Armament, Shadow Systems, Suarez International, Tactical Kinetics, ZEV Technologies.

G5 Mass Driver on G19X by Nolan, Verified Owner, April 23, 2022
I typically don't leave reviews very often but wow I could not help myself with this product. Shot 200 rds through my G19X today with the mass driver and it was ridiculous how much the recoil is mitigated. The recoil of 9mm with this comp is seriousl...

G5 Mass Driver by Tackleberry, Verified Owner, May 3, 2023
I've been a competitive shooter for many years now and have used many different types of compensators, some good, some not so much. I had my doubts about this Mass Driver but took a chance and installed it on my gen 5 Glock 17. Took 400 rounds of 9mm...

Strike Industries G5 Mass Driver Compensator by Mo Takidin, Verified Owner, October 19, 2022
This product works perfectly as a compensator however it does not work with the Glock 100% there is something wrong. When I start shooting the slide won't go back to the front the way it should. I thought, in the beginning, it will be a matter of t...

Product Info for Strike Industries G5 Mass Driver Compensator

Blend with your target with this legal and functional Strike Industries G5 Mass Driver Compensator that vastly reduces your felt recoil. Strike Industries designed these Reduction Parts to be the closest thing a compensator can get to a space travel concept, as the name suggests. With the Strike Industries G5 Mass Driver Compensator, a reciprocating mass and increased inertial mass are counteracted by the expanding gasses from your round after it is discharged, greatly diminishing your felt recoil. However, it is wise to remember that recoil is still a reality, and adding a compensator barrel can decrease reliable cycling on a regular handgun. So, to mitigate your weapon's recoil, you need to properly install the compensator first. Thankfully, this threaded compensator has a widened bore to prevent your stray shots from causing damage. You can use this device in conjunction with a Glock aftermarket threaded barrel to get the "aftermarket" look, but we recommend pairing this compensator with a non-threaded barrel instead. This device even has a 2.5mm relief cut at the top rear to prevent damage to the face of the slide. 50 state legal, this Strike Industries G5 Mass Driver Compensator is a simple way to reduce your recoil to a bearable level. Your recoil is what matters most when you're tinkering with your weapon. Stay comfortable and nimble with the Strike Industries G5 Mass Driver Compensator for Glock.image
