yes it sure will for foster style slugs a cylinder or IC choke will be best however if you are looking for the best accuracy possable you should try the SABOT rifled slugs along with a Carlson's rifled choke apexbowhunting.com/product/carlson-s-rifled-win-browning-mossberg-500-invector-12-gauge-choke-tube-81128/

Yes, you can shoot slugs. 👍🏻‼️

Yes you can. Foster type slugs thru a modified or improved choke are preferred.

Good morning to you!! Yes, the Mossberg 940 Pro JM 12-gauge can shoot rifled slugs. Because it has a smoothbore barrel, it is best suited for Foster-type (rifled) slugs rather than sabot slugs. Using improved cylinder or modified chokes is recommended for the best accuracy and safety; do not use a full choke with slugs.
Choke Selection: Use more open chokes like Improved Cylinder (IC) or Modified.
Slug Type: Use rifled/Foster-type slugs for best performance in the smoothbore barrel.
Accuracy: The 24-inch vent rib barrel, while designed for competition, can accurately shoot slugs for hunting or tactical purposes at appropriate ranges.
Compatibility: The gun is designed for 2.75" or 3" shells, making it suitable for standard, powerful slug loads.
Hope this helps. Have a good rest of your day.

Yes, the Mossberg 940 Pro JM 12-gauge shotgun will shoot rifled (Foster-type) slugs. Because it has a smoothbore barrel, it is designed for rifled slugs rather than sabots. It is recommended to use Improved Cylinder or Modified chokes for best performance, and to avoid full chokes.
Optimal Use: Foster-type "rifled" slugs are best for the smoothbore barrel, as explained in this Mossberg Owners forum thread.
Choke Selection: Do not fire slugs through a full choke; Improved Cylinder or Modified chokes are recommended for better accuracy and safety.
Performance: The 940 Pro JM is known to handle a wide range of loads, including 1-ounce slugs.
Compatibility: Some users have reported issues with cycling certain slugs, while others have found them to function flawlessly
