Tandemkross Ultimate Trigger Kit for Ruger Mark IV and Mark IV 22/45 Red

This kit replaces the whole fire control group in a Ruger Mark IV or Mark IV 22/45 rather than just swapping the trigger shoe. The red Victory trigger is skeletonized with a flat textured face and carries screws for pre travel and over travel, so the break can be tuned to where you want it.

Behind it, the Thunder hammer is lighter than the stock part for a faster lock time, and the Lightning sear is radiused so it breaks clean instead of dragging. The Blast Shield magazine disconnect keeps the hammer and sear out of the fouling a rimfire throws off and lines the magazine up on the way in. All the parts are heat treated tool steel.
