TandemKross Ultimate Trigger Kit Features The TandemKross Ultimate Trigger Kit is a completely new take on the Ruger Mark IV and Mark IV 22/45 fire control system with every component redesigned rather than simply polished. The radiused sear and hammer interface produces a clean crisp and repeatable trigger pull at approximately 2 to 2.5 pounds a significant improvement over the factory trigger feel. A lubricant coating applied to the hammer and sear provides a consistently smooth interface straight out of the box without requiring a break-in period. The lighter TandemKross hammer reduces mass resulting in higher velocity and decreased lock time for a faster more responsive trigger break. Built from highly impact and wear resistant heat-treated S7 hardened tool steel the kit is engineered for long-lasting optimized performance under repeated use. A neutrally balanced drop-safe sear design maintains safety standards while still delivering the lighter pull weight shooters are after. Finished in a bright red that stands out against the Mark IV s factory finish the kit also adds a visual upgrade alongside its functional improvements. Weighing just 0.3 ounces the TandemKross Ultimate Trigger Kit is a focused upgrade for Mark IV owners seeking a safer smoother and lighter trigger.
