Again in January 2020, the 940 JM Professional autoloading shotgun hit the scene, shaking up aggressive capturing with its slick design and ready-to-roll options. Teaming up with champ shooter Jerry Miculek, Mossberg simply improved upon these 12-gauge beasts by together with optic-ready fashions within the present lineup. This mannequin options the Protect RMSc footprint so you’ll be able to slap on these micro dot sights with ease. Additionally, setting this 12-gauge, 3-inch competitors autoloader aside is its black anodized receiver and complementing Multicam Black camo inventory and forend.
Now, let’s discuss upgrades. Constructing upon the trusty Mossberg 930, the 940 JM Professional steps it up with a gasoline system that retains chugging for as much as 1,500 rounds earlier than needing a scrub. It breezes by means of each 2.75 and 3-inch factory-made ammo, even when it’s packing a stable 1 oz or extra.

One challenge I bumped into was that not all purple dots made for a Protect RMSc lower will work with the 940 JM Professional. Particularly, I couldn’t mount the Vortex Defender-CCW. It was barely too lengthy and the again of the housing hit the angled lower on the receiver. I’m not certain if this was a purple dot drawback or an optic lower drawback, however an Sig ROMEOZero elite match with out a difficulty so I used to be 2/3. Additionally, the screws that got here with the Holoson SCS Carry had been too lengthy. The left screw labored simply advantageous, however the proper one caught by means of the highest of the receiver and hit the bolt, retaining the shotgun from biking.

Furnishings
This new variant of the 940 JM Professional additionally options Multicam Black camo for each the inventory and forend. Whereas wanting nice, the grip of the artificial inventory and forend additionally characteristic Mossberg’s mildly aggressive texturing.

Constructed for 3-gun competitions, I’d have preferred it to be barely extra aggressive, however it nonetheless does the job nicely.

When pulling previous, there’s a little bit of creep earlier than the set off breaks, however it’s not unhealthy. I measured the pull weight to be between 3.5-4lbs, however after the break, the reset is superb. This can be very brief and locations your finger proper again on the wall prepared for that subsequent shot. In relation to competitors weapons, having a set off like that is important.
