The Panzer Arms FS1 Pro in 12 gauge with a 20-inch barrel and Black/FDE two-tone finish (brand part no. FS1-PRO) folds its stock for a more compact stowed length, giving shooters an easier gun to store or transport without losing barrel length. Panzer Arms accepts a 3-inch chamber, feeds a 4-round magazine for a 4+1 total capacity, and pairs the barrel with an interchangeable mobile choke system for versatile pattern control. Among folding-stock semi-auto shotguns, the FS1 Pro favors shooters who want a compact, easy-to-store 12 gauge for home defense or truck-gun duty.
