Lone Wolf Distributors is the originator of this design, so don't be fooled by imitators.

Lone Wolf Distributors Universal Trigger Housing (LWD-UTH) gives you a competitive edge by completely eliminating Glock trigger over travel. Trigger over travel is defined by: "The amount of rearward movement after the firing pin has been released". The results of eliminating trigger over travel (wasted movement) are; smoother trigger reset, faster doubles, faster splits and overall premium trigger performance.

The LWD-UTH includes a new style trigger housing with ejector, polished trigger stop, set screw for over-travel adjustment, and allen wrench. This drop in part replaces your current trigger housing. The easy to follow instructions allow you to completely remove your trigger "over travel" in seconds. No gunsmithing is required. The LWD-UTH allows you to "turn it on or turn it off" at will.

Product Features:

-Works in OEM or Timberwolf Frames
-includes a set screw and wrench for over-travel adjustment
-Drop-in install in seconds
-Available for all uses, but highly recommended for plinking, target or competition use
-LWD-UTH-9 fits 9mm pistols 17, 19, 26, 34 Gen3 and Gen4

Note: This does not fit Gen5 models

If you are using a UAT (Ultimate Adjustable Trigger) with a UTH (Universal Trigger Housing) you don't need to adjust both over-travel screws. Pick one and leave the other unadjusted.
