I finally finished (for now) my Ruger Mark IV 22/45 Lite. The only thing on it from Ruger now is the frame. The trigger was replaced with a Volquartsen Accurizing Kit and a Tandemkross Victory Trigger.
There is a VQ LLV-6 in. barrel and compensator along with a Bill Striplin thumb Rest and Extended Safety.
Trigger Pull is a nice and consistent 2 lbs.
