Mossberg 940 SPX 12 Gauge Semi-Auto Shotgun, 18.5″ Barrel

Product Description

The Mossberg 940 SPX is a 12 gauge semi-auto shotgun with an 18.5″ barrel. It holds 7+1 rounds and has a 3″ chamber, so it handles 3-inch shells as well as shorter ones.

This model is finished in FDE Cerakote and is fitted with ghost ring sights. A ghost ring setup is a fast, open way to line up a shot, and it works well on a shotgun meant for close to moderate range. The semi-auto action means one trigger press per shot without working a pump.

Who it suits

The 940 SPX fits shooters building a home-defense shotgun, and it also suits range days, practice sessions and shotgun competition. The 18.5″ barrel keeps the gun handy indoors and in a vehicle, while the 7+1 capacity gives you a solid supply before a reload.

Good gear to pair with it includes a quality sling, a shell carrier or side saddle, and a padded case for transport. Eye and ear protection are a must for any session. Pick up a cleaning kit sized for 12 gauge, plus a few boxes of the loads you plan to run, so you can learn how the gun patterns and cycles with your ammunition.
