Mossberg's 940 JM Pro was designed with input from World Champion shooter Jerry Miculek as a purpose-built 3-Gun Competition winner. This fast shooting shotgun is outfitted with a durable gas system that features a corrosion resistant nickel boron coating on all of the internal parts and a cleaner running gas vent that allows the 940 JM Pro to run reliably for up to 1500 rounds between cleanings. The durable gas system is topped off with a competition level loading port, elevator, and follower. The 940 JM Pro's stock is adjustable for drop and length of pull, and the receiver is drilled and tapped for optics. Additionally, select models of the 940 JM Pro are available with extended magazine tubes with a capacity of 9+1 shells.
