Sun City Model 320 Field Grade 12 Gauge Pump-Action Shotgun, 28″ Vent-Rib Barrel, Win-Choke, Synthetic Stock
Built by Sun City Machinery and imported under the Stevens banner by Savage Arms, the Model 320 Field Grade blends the proven Winchester 1300-style rotary-bolt action with modern, maintenance-friendly synthetic furniture. A carbon-steel, 28-inch vent-rib barrel threaded for Win-Choke tubes, a 3-inch chamber, and dual action bars give this full-size pump the versatility and smooth cycling hunters and clay shooters expect—at an MSRP that keeps it firmly in the value category.

What’s Included
- Sun City Model 320 Field Grade 12 Gauge shotgun
- One Win-Choke compatible removable choke tube (installed)
- Factory-installed magazine plug (restricts capacity to 2 + 1)
The Model 320 operates on a familiar pump-action layout but uses a rotary bolt that unlocks quickly for faster cycling—an approach borrowed from the classic Winchester 1300 design. Dual action bars help prevent binding under rapid operation.
Its 28-inch carbon-steel barrel sports a ventilated rib for quick sight alignment and heat dissipation. The muzzle is threaded to the common Win-Choke pattern, allowing easy swap-out of choke tubes to match upland, waterfowl, or clay-target roles.
Synthetic furniture keeps weight down and shrugging off weather. The straight-grip stock includes a molded cheekpiece, a 13.5-inch length of pull, and a recoil pad; the forend adds diagonal stippled panels and finger grooves for a firm purchase.
An aluminum-alloy receiver and matte-black finish throughout resist corrosion while maintaining a low-glare profile in the field. A gold-colored front bead serves as the sole sighting reference—simple, durable, and fast.
Capacity is 5 rounds in the steel magazine tube, but the factory plug limits it to 2 + 1 for migratory-bird compliance. Remove the plug when regulations permit to return to full capacity.
