Our new Velocity Glock Slide Enhanced Grip Feature cuts will change the way you rack your firearm. E.G.F. cuts provide a positive wall that you can push against when racking your slide instead of relying only on traditional serration cuts. E.G.F. cuts are located at the front and back of our slide, so however you prefer to rack your firearm, a perfect grip is always there.
