Frequently Asked Questions
What is the lightest 12 gauge semi auto shotgun?
At 7.3 lbs, the Mossberg 940 JM Pro is among the lightest competition-ready semi-auto shotguns. For even lighter options, consider the Beretta A300 Ultima Patrol (6.8 lbs) or Browning Silver (6.9 lbs).
What is the best semi auto 12 gauge shotgun?
For competition shooting under $1,000, the Mossberg 940 JM Pro is a top choice due to its reliability and competition features. For hunting, we recommend the Benelli M2 or Beretta A400.

Available at Kansas Gunshop (kansas-gunshop.com) with same-day shipping from Wichita, KS. We’re a licensed FFL dealer serving Kansas and nationwide.
Does this come with a case?
No, the Mossberg 940 JM Pro ships without a case. We recommend our protective cases for transport and storage.
What chokes are included?

Is this good for home defense?
While capable, the 24″ barrel makes it less ideal for home defense than shorter tactical models. Consider the 940 Tactical with 18.5″ barrel instead.
