The Professional Model is strictly an NFA gun we build exclusively for military and law enforcement professionals. The Professional Model is on duty across the country every hour of every day with officers who have complete dependence on the reliability of their weapon. It incorporates the features demanded most in their defensive shotguns: a 14” cylinder-bore barrel with 3” magnum chamber that will handle the ammunition your mission demands – and the included magazine extension tube offers increased capacity for a total of 6 rounds. We include an extra-power heavy-duty stainless magazine spring for sure shell feeding in any situation, and a high-visibility, non-binding follower to indicate an empty-magazine tube at a glance. The Professional Model also includes your choice of a four or six round receiver-mounted Sidesaddle shell carrier – in a critical re-load situation your extra ammo is quickly available in a no fumbling, load-by-feel manner.
