Killer inovations - Killer Innovations Velocity Glock 17/19 Gen 3 Barrel Compensator

I decided to try the killer innovations comp cuz I had bought a ported barrel for another build and really liked the way it shot it reduced recoil noticeably but it would black out my trijicon front sight post and make the inside of my slide extremely dirty. So I decided to try out a comp on a different build and I really like it, it doesn't affect my front sight post and doesn't make the pistol extremely dirty plus it shoots really well. I did have to buy a 13 pound spring to make it cycle though so if you're thinking about getting one I recommend you get the 13 pound spring to go with it
