The pin is designed to eliminate wear in and around the hole. The steel pin body has a black oxide finish. The button also has a drilled cross hole which allows for the installation of a seal wire to prevent tampering with the guns internals. This enhanced version has an end cap to ease in pin removal and installation and also prevents any debris from entering the internal parts of the pin.
