"The Mossberg 930 is a versatile, gas-operated 12-gauge semi-automatic shotgun chambered for both 2-3/4"" and 3"" shells, widely popular for hunting, sporting clays, and tactical home defense applications. Core Specifications & Features • Action: Gas-operated, self-regulating dual gas-vent system designed to vent excess gas, reduce felt recoil, and cycle a broad range of loads from target shells to heavy magnum and slug ammo. • Capacity: Varies by model, ranging from 4+1 rounds for standard field/hunting and select tactical versions up to 7+1 or 8+1 rounds on extended magazine tube variants like the SPX. • Safety: Convenient, ambidextrous top-tang safety mounted on top of the receiver, making it easily accessible for both left- and right-handed shooters. • Ergonomics & Fit: Includes a stock drop spacer system on synthetic models to allow custom horizontal and vertical adjustments to the drop-at-comb. Tactical models often feature oversized, knurled charging handles and drilled/tapped receivers ready for optics mounting. • Available Series: Offered across specialized configurations including Hunting, Tactical/SPX, JM Pro-Series, and Sporting editions tailored for distinct shooting sports and operational needs."
