The Tac-Con 3MR Trigger system is a drop-in, three-mode fire control system consisting of safe, match-grade semi-automatic and the Tac-Con-patented third mode of operation. The third mode provides a positive reset, which transfers the force from the bolt carrier through the trigger assembly to assist the trigger back onto the front sear, giving the firearm the fastest reset possible. Both semi- and third-mode positions feature a non-adjustable 4.5-pound trigger-pull weight with zero take-up and no overtravel. Why 4.5 pounds? Because most law enforcement agencies limit any trigger used for duty to 4.5 pounds and above. MSRP $495.
