This items was developed to significantly reduce felt trigger slap on our mini 9 and full size 9mm pistols and carbines. It is a permanent replacement to the disconnected hammer that provided similar relief, but unfortunately had design feature that required the disconnect to be replaced after a varied qty of rounds fired, depending on the barrel length and ammo type.
Simply slide the shoe over the existing trigger and tighten down the included fasteners. The system disperses the return energy of the sear plate into the trigger over a wide and flat surface.
Takes 5 minutes to install.
