This review covers the Strike Industries Mass Driver G4 compensator for Glock Gen 4 pistols (19, 23, 32). It highlights the key benefit of not requiring a threaded barrel, making it legal in restrictive states. The installation is straightforward, and live-fire testing demonstrates a significant reduction in muzzle rise and felt recoil, improving follow-up shot speed and accuracy. While effective, the added length may impact concealed carry.
