Men and women in uniform need a rugged, dependable firearm they can rely on day in and day out, no matter the conditions. Mossberg's 590A1 shotguns have posted the credentials and track record over several decades to earn their trust.

Specifications include a heavy-walled parkerized barrel, metal trigger guard assembly, metal safety button, and an upgraded magazine tube that can easily be opened for cleaning and is readily adaptable for a magazine extension.
