The Panzer Arms FS1 Pro 12 Gauge Semi-Auto Shotgun blends a folding gas-operated system with a modern, two-tone Black and Flat Dark Earth Cerakote finish for a refined, purpose-built design. Its 20" black shrouded barrel, M-LOK handguards, and Picatinny rail along the receiver create a versatile platform for lights, lasers, or optics, while the synthetic stock with adjustable cheekrest and integrated shell holders keeps extra rounds and a consistent cheek weld close at hand.

This FS1 Pro configuration is ideal for home protection, training, and range use, offering a 3" chamber and 4+1 tubular magazine capacity with compatibility for Beretta/Benelli Mobil choke tubes. Glock-style fiber optic sights support fast, intuitive target acquisition, and the folding layout makes storage and transport more convenient without sacrificing shootability. Thoughtful ergonomics and reliable semi-automatic operation reflect Panzer Arms’ focus on practical innovation and accessible performance.
