Dude I've installed Trijicon tritium sights on all my glocks with a brass punch and a hammer. If that would break your sight it would be a pos.
Some of the HD sights come with a shorter screw for the front sight. Dont install the factory Glock screw in the Trijicon sight. It will break the tritium vial.
