T3 Professional Development's Review of Herrington Arms Glock 19/17/26 HC9XL 3.0 Pistol Compensator
It works great… For installation just learn how far you can thread it on without interfering with cycling. Do some dry slide racking to ensure full function and no slide contact. Avoid 115 grain. 124 or 147 work best.
