The O.F. Mossberg & Sons Mossberg 930 Combo Deer/Waterfowl and 930 Combo Field/Security are part of Mossberg’s affordable 930 Hunter 12-gauge semi-automatic shotgun lineup. First let’s discuss the 930 Combo Deer/Waterfowl, then the 930 Combo Field Security.

The 930 Combo Deer/Waterfowl is an all black gun. It stands apart from its siblings by having two easily swapped 12-gauge barrels. One is 24” and rifled while the other is 28” and topped with a vent rib.

The 24” length fully rifled slug barrel shortens overall length to 44.5”. It sports a matte blued finish, and it’s topped with adjustable rifle sights. That’s so you don’t have to do any adjustments to the sights when you swap barrels.

The 28” length barrel makes the overall length 48.5”. It is matte blued and works with the included trio of Briley Accu-Set Skeet, Improved Cylinder and Modified chokes. These are beautifully crafted with tapering flutings and come with their own carrying case. The 28” barrel’s vent rib sits atop a collection of 12 vertical bridge piers. The repetitive frequency is functional, but it also creates a visual elongation of the gun.

Either way, length of pull is a neat (and comfortable) 13.875”. Weight is 7.5 pounds. The Combo’s 3” chamber handles 2 ¾” and 3” shells. Magazine capacity is five 2 ¾” or four 3” shells making overall capacity 5+1 or 4+1 respectively. But 930s also come with a magazine plug that limits capacity to just two shells to stay abreast of regulations.

The stock has a standard profile. Behind it is the thick black “checkered” recoil pad. It’s skeletonized and soaks up plenty of recoil. There are also integrated sling studs at front on the magazine cap and in back on the stock’s bottom slope.

The 930 Combo Field/Security is very similar to the aforementioned shotgun except it has an 18.5” tactical security barrel instead of the 24” rifled barrel. This 18.5” barrel has a bead sight and a cylinder bore choke. There is enough difference in length between the 28” and 18.5” that weight goes from 7.5 pounds down to 6.75 pounds when you swap to the shorter barrel. This configuration’s overall length should be 29”.

All 930s feature drilled and tapped receivers to mount a Picatinny rail. The lineup’s synthetic forend and stock models have an adjustable stock drop spacer system (that includes spacers and retention plates) for easy personalization. These guns also have a dual gas-vent system that reduces felt recoil.

A cool trait of 930s is how you get a forend and stock with nice contours and excellent texturing on both parts. Moving back, you’ll find the ambidextrous tang safety with the standard forward is safe and rearward is ready to fire. An easy to see silver cocking indicator automatically protrudes when the gun is cocked. At bottom is a quick-empty magazine release button. Push it and all loaded shells easily drop out.
