For the discriminating shooter demanding the utmost performance from their trigger, Timney’s CZ 457 is designed to be robust, user-friendly, adjustable for pull weight and over travel, yet delicate enough to be set with a pull weight as low as 10 ounces or up to 2 pounds. Every part of the trigger is machined using state-of-the-art technology – no skimping with metal injection molding or stamped, old-school parts. Timney’s CZ 457 replacement trigger features our new Sear Engagement Adjustment Lock designed, (SEALd) that ensures a user-friendly experience. The triggers sear and trigger shoe are precision-machined, heat treated to 56 Rockwell with a black oxide trigger coating and an NP-3 coated sear for maximum lubricity and a lifetime of reliable performance. The CZ 457 trigger is backed by the legendary Timney No Hassle, Lifetime Warranty.
