Specs at a glance
About this product
The Mossberg 940 JM Pro is a competition-grade, semi-automatic 12-gauge designed for speed and reliability in sport shooting. It pairs a 24-inch vent-rib barrel with a 3″ chamber and a durable gas system engineered for extended intervals between maintenance. The receiver is finished in tungsten-gray anodizing and the shotgun ships optic-ready for Shield RMSc-pattern micro dot sights while retaining a HiViz TriComp front fiber optic sight for rapid acquisition. Controls and ergonomics — including an adjustable synthetic stock and an enlarged charging handle and elevator — are optimized for competitive loading and fast follow-up shots.
