Panzer Arms FS1-Pro Folding Tactical 12 Gauge Shotgun 20" Barrel - 4 Rd

The FS1 PRO Folding Semi-Automatic Tactical Shotgun is a next-generation defensive platform designed to deliver compact portability, rapid deployment, and adaptable performance in high-pressure environments. Built around a rugged 7075-T6 receiver and a proven gas-operated system, this 12-gauge shotgun combines modern tactical ergonomics with field-ready durability for home defense, duty use, or professional applications.

Its defining feature is the folding stock design, which dramatically reduces overall footprint for transport, storage, and rapid deployment without sacrificing shooting stability. Chambered for 3” shells and equipped with a versatile magazine system, the FS1 PRO offers dependable firepower with configurable capacity for a wide range of defensive scenarios.

Engineered for speed and control, the shotgun features Glock-style fiber optic sights for fast target acquisition, while the integrated Picatinny rail system allows for mission-specific accessory mounting such as lights or lasers. Combined with multiple onboard shell storage points and an adjustable cheek riser, the FS1 PRO is built for intuitive handling and rapid response under stress.

A protective barrel shroud, durable Cerakote finish, and aggressive FDE/black tactical styling ensure both operator safety and long-term resilience in harsh conditions. The result is a highly adaptable folding shotgun designed for users who need compact readiness without compromising capability.
