Our V-Port barrel porting will decrease muzzle flip while maintaing reliable cycling without the need to run a lighter recoil spring. Currently this modification is only available for 9mm, 40 s&w and 45 acp chambered glocks. This modification will not work WITHOUT a top port. You will need to purchase our slide top port milling for proper function unless you have a G34/35 with factory top port. We can not guarantee that special coated barrels such as DLC/PVD will not chip around the porting due to endless variances in coating process and hardness.
