Description
There is a reason the pump action 12 gauge is still the default answer for home defense, and the Stevens 320 Security makes that answer easy to reach. This version of the 320 comes set up from the factory with the features most folks end up adding to a defensive shotgun anyway: a barrel-mounted heat shield, a one-piece Picatinny rail up top, and a black synthetic stock with a full pistol grip that gives you solid control during quick follow-up shots. The 18.5 inch barrel keeps the whole gun at just over 39 inches, short enough to move through a hallway without feeling like you are carrying a goose gun.
Inside the 320 Security's Action
Under the matte black finish, the 320 runs on a rotary bolt paired with dual slide bars, the same basic recipe that has kept pump guns cycling reliably for decades. The action loads from the bottom and ejects to the right, feeding from a 5+1 tubular magazine. The 3 inch chamber handles everything from light target loads for practice up to full-power buckshot and slugs, and the fixed cylinder bore choke is exactly what you want for defensive distances where patterns need to open up fast.
Sighting and Setup on the Stevens 320
A bead front sight keeps things simple out of the box, and the receiver-mounted rail is there when you want to add a red dot or other optic. The heat shield over the barrel is not just for looks either; run a fast string of shells and you will appreciate having something between your hand and a hot barrel. At 7.2 pounds with a 13.75 inch length of pull and a rubber recoil pad, it soaks up 12 gauge recoil better than you might expect from a defensive gun at this size.
The 320 line has built a following by delivering features usually found on pricier shotguns without cutting corners on function. For a bedside gun, a truck gun, or a knockaround pump for the range, this one covers the bases and then some.

Frequently Asked Questions
Does the Stevens 320 Security have a full buttstock or just a pistol grip?
This model has a full-length black synthetic buttstock with an integrated pistol grip, not a pistol-grip-only setup. That gives you a proper cheek weld and shoulder mount with the added control of a vertical grip. It also comes with a rubber recoil pad and a 13.75 inch length of pull.
Can the 320 Security shoot 3 inch shells?
Yes, it has a 3 inch chamber, so it handles both 2.75 inch and 3 inch 12 gauge shells. That covers everything from light birdshot for practice sessions to full-power buckshot and slugs for defensive use. Keep in mind capacity is 5+1 with 2.75 inch shells.
Can I mount a red dot on the Stevens 320 Security?
You can. This model ships with a one-piece Picatinny rail already mounted on the receiver, so a red dot or similar optic bolts right on. If you prefer to keep it simple, the bead front sight works fine on its own for typical defensive distances.
Is the choke on this shotgun interchangeable?
No, the 320 Security uses a fixed cylinder bore, which means no choke tubes to swap or lose. Cylinder bore is the standard choice for defensive shotguns since it patterns buckshot well at close range and shoots most slugs without issue. If you want interchangeable chokes for hunting, look at the field versions of the 320 instead.
