Timney’s customers have been asking for a dedicated CZ Model 457 rimfire trigger for hunting and competition shooting. They asked, Timney delivered. 

For the discriminating shooter demanding the utmost performance from their trigger, our 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.  Our CZ 457 replacement trigger features our new Sear Engagement Adjustment Lock designed, (SEAL’d) that ensures a user-friendly experience.

The trigger’s 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
