The Glock Plug is designed to securely snap into the open cavity which is at the bottom of the Glock handle just behind the magwell. This cavity is open at the top of the receiver just under the trigger assembly and firing pin. When the plug is installed, it will not allow debris such as dirt, dust, sand, rain, lint, snow, etc. to enter the open cavity and reach the trigger assembly and firing pin. The Plug also eliminates any possible snagging at open cavity. It is currently used by law enforcement and military worldwide and takes just a few seconds to install. The Glock Plug is a very inexpensive way to protect the Glock pistols internal parts.
