Mossberg 930 Home Security 12 Gauge Semi-Auto Shotgun, 18.5" Barrel, Fixed Cylinder Choke
The Mossberg 930 Home Security is a purpose-built 12-gauge semi-automatic designed for reliable defensive performance. An 18.5-inch barrel with a fixed cylinder choke, a self-regulating dual-gas-vent system, and a 4+1 capacity combine to give this model fast follow-up shots and minimal maintenance needs. Its matte-blued steel and black synthetic furniture keep weight down and durability high, while familiar Mossberg ergonomics—such as the tang-mounted safety—make operation intuitive for anyone used to the brand’s pump guns.

What’s Included
- Mossberg 930 Home Security 12 Gauge shotgun
Introduced in 2005, the 930 series remains Mossberg’s flagship semi-auto line. This Home Security variant uses a gas-operated action that automatically adjusts to different load pressures, promoting dependable cycling from standard 2 ¾-inch shells up to 3-inch magnums.
The 18.5-inch carbon-steel barrel wears a fixed cylinder choke, ideal for defensive patterns at close range. A brass bead front sight offers a simple, snag-free aiming reference.
Controls are purpose-driven. The EZ-Empty magazine-release button lets you unload the tube without running shells through the action, and the tang safety mirrors the location found on Mossberg 500/590 pump guns, simplifying cross-training.
Durable black polymer furniture includes a pistol-grip-style stock with molded checkering, a ventilated recoil pad, a 14-inch length of pull, and sling-swivel studs ready for a carry strap or tactical sling.
With its compact 4+1 capacity, matte-blued finish, and competition-proven mechanics, this 930 provides a solid foundation for home defense or future tactical upgrades.
