Product Description The TANDEMKROSS Ultimate Trigger Kit for the Ruger Mark IV and Mark IV 22/45 in Red is a completely redesigned fire control system that delivers a dramatic improvement in trigger performance, safety, and reliability. Every component of the trigger mechanism has been re-engineered from the ground up, featuring a lubricant-coated hammer and sear for a consistently smooth hammer-sear interface straight out of the box. The lighter TANDEMKROSS hammer reduces lock time by increasing velocity while decreasing mass, resulting in faster, more consistent ignition. Whether you are competing in rimfire competitions, hunting small game, or simply want a high-performance trigger system in your Ruger pistol, this kit is a must-have upgrade that installs easily and provides an unrivaled boost in performance and reliability. American-made and guaranteed for life. Product Highlights Victory Trigger: Flat-faced, skeletonized design for enhanced control with a textured trigger face for a no-slip grip in any condition; 100% adjustable pre- and post-travel. Thunder Hammer and Lightning Sear: Safely and reliably decreases trigger pull weight while delivering a consistently clean and crisp trigger break. Blast Shield Magazine Disconnect: Promotes proper magazine alignment for consistent feeding while shielding the hammer and sear from debris and buildup, simplifying maintenance. Complete Fire Control Replacement: Every part of the trigger mechanism has been redesigned for reduced pull weight, improved safety, and enhanced reliability right out of the box. American-Made and Lifetime Guaranteed: Built in the USA and backed by a lifetime guarantee for long-lasting confidence in performance.
