Handling in the Field
Mossberg shotguns are built to be dependable year after year with simple maintenance. This model mounts naturally and swings smoothly, and it is ready for the field, range, or home defense right out of the box.
Action and Trigger
The pump action is fast and reliable with nearly any load. Rack the forend fully for each shot, and use the top-mounted safety, which works for left and right-handed shooters.

The 12 Gauge Cartridge
The 12 Gauge is the most versatile shotgun chambering, with loads for everything from clays and birds to buckshot and slugs.
Setup and Accessories
Set your shotgun up for its job: hunters will want a sling and a few choke tubes, clay shooters may add a recoil pad, and a home-defense setup benefits from a weapon light. Pattern every load and choke combination you plan to use.
Ownership Tips
Read the owner’s manual fully before your first range trip, and keep the manual, box, and receipt with your records for warranty service and resale. Unload the shotgun and confirm it is empty before cleaning. Field-strip it according to the owner’s manual, scrub the bore with a brush and patches, and wipe carbon from the action and choke threads. Apply a light coat of quality gun oil to the contact points, and wipe the exterior with a lightly oiled cloth before storage.
State Laws
Magazine capacity limits, feature restrictions, and transfer rules vary by state and locality. Check your local laws before ordering, and ask your receiving dealer if you are unsure whether this configuration is legal where you live.
