* Important: Porting can change how the firearm functions. We try to test with multiple types of ammunition, but your results may vary from ours. You might find it runs well with certain types of ammo and not so well with others. You might have to change out the recoil spring. Because of all the variables involved we cannot guarantee 100% reliability. Porting redirects/vents gasses out of the top of the barrel/slide. These gasses are hot!! Use with caution & follow all firearm safety rules. *
