Description

Hornady Critical Duty .357 Sig ammunition uses a 135-grain FlexLock projectile engineered for consistent expansion and barrier performance in duty contexts. The FlexTip polymer tip reduces clogging and helps initiate expansion, while the InterLock jacket-to-core band improves weight retention. Nickel-plated brass cases and low-flash propellant are included to aid corrosion resistance and reduce visible muzzle flash. This load is presented for duty and defensive applications where barrier performance and reliable feeding are priorities.
