The CZ 457 Thumbhole Varmint Laminate combines the heavy varmint-profile barrel with a laminate thumbhole stock — a pairing that prioritizes weather resistance and consistent grip angle simultaneously. The laminate stock resists humidity cycling that warps walnut, and the thumbhole geometry maintains consistent hand position across extended shooting sessions. The 457's adjustable trigger and cold-hammer-forged heavy barrel are unchanged.
