I saw the Glock grip plugs in some magazines and thought that they may be beneficial to preventing any foreign material from entering the gun. The ad also claimed to aid in rapidly changing magazines. I asked at a local tactical shop and the guy explained that the plugs actually stop the discharge of carbon and are not recommended for those who shoot alot and often due to it creating a dirtier weapon. Does anyone have any experience with these and if so are they more harm than good????...thanks
