Parker Mountain Machine Barrel/ Comp- Review
This review by Regular Guy Training LLC focuses on the Parker Mountain Machine (PMM) barrel and compensator system for Glock Gen 5 handguns. The presenter highlights PMM's innovative design that indexes the compensator over the slide and into the dust cover, preventing holster issues even if it comes loose. The installation is compared to a standard rifle muzzle device, utilizing spacers for precise alignment. Performance-wise, the single-port compensator is noted to reduce felt recoil impulse without significantly robbing energy, making it suitable for carry and duty use.
