Product Description The TANDEMKROSS Ultimate Trigger Kit is the definitive fire control upgrade for the Ruger Mark IV and Mark IV 22/45. This comprehensive kit completely reimagines the Ruger Mark IV 22/45 trigger mechanism, redesigning every component to reduce trigger pull weight, boost safety, and maximize reliability. The kit features a flat-faced, skeletonized black trigger crafted from heat-treated S7 hardened tool steel with a textured finish for a positive grip feel. A lubricant coating on the hammer and sear delivers a consistently smooth hammer-sear interface straight out of the box. The lighter TANDEMKROSS hammer reduces lock time through higher velocity and decreased mass, while the included Blast Shield Magazine Disconnect promotes proper magazine alignment for consistent feeding and protects the fire control components from debris. The built-in pre- and post-travel adjustability via the Victory Trigger design allows shooters to fine-tune their pull for fast, clean, and repeatable resets. This kit is a must-have for rimfire competition, small game hunting, or any shooter seeking a high-performance trigger in their Ruger Mark IV 22/45. Note: This is a match set only; do not use any other brand of sear and hammer with this kit.
