2-port Glock Compensator, fits your 9mm Glock (17, 19, 26, 34) or .40 Caliber Glock (22, 23, 27). This device directs outward gases upward, accomplishing the twin goals of shooting flatter and less felt recoil.
The size of the compensator will make a Glock 19 the same length as a Glock 34 for holster fitment. It is the same dimensions as the slide, and won’t interfere with holstering.
A threaded barrel is required.
