TandemKross Ultimate Trigger Kit for Ruger Mark IV and 22/45

TandemKross put the Ultimate Trigger Kit together for Ruger Mark IV owners who want more out of the pistol than the factory trigger gives them. Instead of sourcing upgrade parts one at a time, the kit gathers them into a single install. It covers both the standard Mark IV and the Mark IV 22/45 grip frame, so one part number handles either pistol in the safe.

Rimfire competition and high volume range work are where a trigger upgrade earns its keep. A cleaner break and a shorter reset show up on the target once you are running strings of fire rather than slow fire groups. The kit's parts are finished in black, so the change is felt rather than seen.
