Key Features
- Double-barrel pump action: Two 18.88-inch barrels let you fire two rounds per pump cycle. Why it matters: You get twice the stopping power without fumbling for a reload.
- 14+2 round capacity: Fourteen shells in the dual magazine tubes plus two in the chambers equals sixteen total. Why it matters: That’s enough firepower to handle multiple threats or a long day at the range without constant reloading.
- Ambidextrous controls: Safety and pump slide release work for both left- and right-handed shooters. Why it matters: Teaching a left-handed family member? No need to swap parts—everyone can shoot safely right out of the box.
- Picatinny rails on forend and receiver: Full-length top rail and MOR rails on the forend accept lights, lasers, or optics. Why it matters: Mount a weapon light for home defense or a red dot for quicker target acquisition.
- Co-molded rubber grip and vertical foregrip: Non-slip pistol grip and composite vertical grip keep your hands locked in place. Why it matters: Even with sweaty hands or gloves, you maintain control during rapid fire.
Who It’s For
This shotgun is built for shooters who want serious defensive firepower in a familiar pump-action platform. It’s ideal for home defense, ranch protection, and sport shooting. Families teaching new shooters will appreciate the intuitive pump action and the ability to fire two rounds quickly for immediate feedback. Youth shooters and beginners can start with light 2.75-inch target loads and work up to 3-inch magnums as their skills grow.
Pros & Cons
Pros: High capacity without a magazine extension; dual barrels mean two shots per pump; ambidextrous safety works for everyone; full-length Picatinny rail for accessories; spreader chokes included for tighter patterns.
Cons: The 9.2-pound weight is heavier than a standard single-barrel pump, which can be tiring during long range sessions. The double-barrel design also makes the forend wider, so shooters with smaller hands may need to adjust their grip.

FAQ
Is the DP-12 reliable with all 12-gauge loads?
Yes, the DP-12 cycles both 2.75-inch and 3-inch shells reliably. Per Standard Manufacturing specs, it handles target loads, buckshot, and slugs without issue. Like any pump, it benefits from a proper break-in period of 50-100 rounds.
Can I mount a red dot or light on this shotgun?
Absolutely. The receiver has a full-length Picatinny rail, and the forend features MOR rails. You can mount optics, lights, lasers, or a combination. Just use quality mounts rated for 12-gauge recoil.
How do I clean the dual barrels?
Clean each barrel separately using a standard 12-gauge cleaning rod and patches. The barrels are fixed, so you clean from the muzzle end. Apply a light coat of oil after cleaning to prevent rust.
Is this shotgun legal in my state?
Because the DP-12 has two separate barrels and two separate magazine tubes, it is classified as a non-NFA firearm by the ATF. However, some states have restrictions on capacity or barrel length. Check your local laws before ordering.
