The internal hammer fired action combined with a flat-face trigger delivers a crisp, consistent break and deliberate reset for controlled, precise shot placement. A locked-breech tempo barrel and match-oriented 5 inch length improve stability and shot-to-shot consistency while reducing felt recoil.
