The Mossberg 590A1 Professional 12-gauge pump action shotgun is engineered for sustained operational demands and consistent reliability. This platform is specified for rigorous duty cycles, offering a robust solution for defensive, law enforcement, and intensive training applications.
Key Features
Heavy-Walled MIL-SPEC Barrel
This model integrates an 18.5-inch heavy-walled barrel, adhering to MIL-SPEC standards. This construction mitigates heat buildup during sustained firing and significantly enhances durability, ensuring consistent performance under adverse conditions.
Robust Construction & Controls
Critical components, including the trigger guard, are fabricated from metal, providing superior resistance to impact and operational stress. The ambidextrous tang safety offers positive manipulation and secure handling for both right- and left-handed operators.
Enhanced Cycling & Lockup
The shotgun’s action is driven by dual action bars, which facilitate smooth and consistent cycling of various shell types. A steel-to-steel lockup mechanism ensures dependable cartridge chambering and ejection, optimizing operational reliability.
Protective Finish
A Tungsten finish is applied to the primary metal components. This protective layer provides resilient, low-maintenance resistance against environmental corrosion, abrasion, and general wear, extending the platform’s service life.
