Mossberg 940 Pro Tactical Review: Best Semi-Auto Tactical Shotgun for Home Defense in 2025?

Introduction

The semi-auto tactical shotgun world has been comfortably dominated by pricey Italian models for quite some time. For those desiring a semi-automatic shotgun for home defense, there were only two choices—shell out big bucks for an Italian-made weapon, or purchase a cheap knock-off brand that few have heard of. That is, until now ... 

Mossberg, one of America’s oldest firearm manufacturers, is successfully bridging the gap by offering the shooting public the 940 Pro Tactical series. Long known for unquestionable workmanship and reliability at an affordable price, the 940 Pro Tactical upholds this tradition with its gas-operated design, optics-ready receiver, and tactical features—all for under $1200.00.

In this review, we will describe why we think it is one of our top picks for a home defense or duty firearm. We’ll give you all its specs, offer pros and cons, and compare it to other similar models. And from a real-world perspective, Colonel Jim Smith, a highly experienced law enforcement officer and 940 Pro Tactical owner, provides his views on using the weapon both for duty purposes and personal defense. 

The Quick Take

Thanks to its combination of reliability, modern design, and user-centric features, the Mossberg 940 Pro Tactical is an outstanding choice for both home defense and law enforcement applications. Built on the proven semi-automatic 940 platform, the Pro Tactical delivers smooth, fast cycling with a gas-operated system that reduces recoil and improves follow-up shot speed.

The 940 Pro Tactical offers intuitive handling and superior ergonomics. Its adjustable stock, M-LOK forend, and oversized charging handle and bolt release make it highly adaptable and easy to operate under pressure. The inclusion of an optics cut for mounting micro red dot sights adds an important edge in target acquisition.

As the name suggests, the 940 Pro Tactical is not a hunting weapon or built for the range. For shooters looking for 940 reliability in either of these two applications, Mossberg offers the 940 Pro Sporting, Turkey, Waterfowl, and Field models, and the 940 JM Pro for competitive shooting.

Mossberg 940 Pro Tactical: Features and Specs

The Mossberg 940 Pro Tactical builds off the brand’s highly successful 930 series by providing an improved gas system for cleaner operation and less maintenance. A true “fighting shotgun,” the 940 Pro Tactical is far from an entry-level weapon and comes standard with many features found only on high-end brands and custom builds; these include an adjustable LOP (length-of-pull) stock, oversized controls, M-LOK forend, and optics-cut receiver.

Like most tactical weapons, the 940 Pro Tactical can be accessorized, but the following are base-model features and specs:

For those seeking an upgraded experience without the need to send their weapon to a custom shop, Mossberg also offers variations of the 940 Pro Tactical such as: 

940 Pro Tactical SPX - Holosun Micro Dot Combo: Includes extras such an innovative forend / heat shield combination, added shotshell carrier, QD mounts, low-profile front sight, and Holosun micro dot HS407K.

Thunder Ranch Series: Per Mossberg’s site, as a result of their “collaboration with Thunder Ranch and the legendary Clint Smith, Thunder Ranch models are purpose-built to be arguably the best personal defense shotguns.” They come loaded with all the top-end features, a complete Patriot Brown Cerakote® finish, and the Thunder Ranch logo.

Pros and Cons of the Mossberg 940 Pro Tactical

The Mossberg 940 Pro Tactical has earned a strong reputation among home defenders and tactical professionals for its blend of reliability, customization, and fast cycling. Like any firearm, it comes with trade-offs depending on the intended use, training level, and operational environment. Here's a breakdown of its key pros and cons to help assess whether the 940 Pro Tactical is the right fit for your needs:

Pros:

• With a price point under $1200, it offers an affordable alternative to premium semi-autos such as Benelli or Beretta.
• The adjustable stock and oversized controls offer a good ergonomic fit for most users, and the tang safety is ideal for standard stocks.
• Optics-ready out of the box and manageable recoil from the upgraded gas system make it a great choice for home defense and rapid follow-up shots.
• After break-in, it provides very reliable cycling of mixed shotgun rounds—e.g., buckshot, slugs, birdshot—and the improved clean-burning system requires minimal cleaning.
• The M-LOK® mounting system on the forend offers easy compatibility for tactical upgrades such as weapon lights or slings.

Cons:

• The 940 Pro Tactical is heavier and bulkier than some competitors (e.g., Beretta 1301 at ~6.8 lbs.), which may affect maneuverability in tight spaces.
• While an affordable weapon in view of its like competitors, it is more expensive than budget pump-action shotguns; this may be a barrier for casual or budget-conscious buyers.
• While the fiber optic front bead site suffices in many scenarios, ghost rings or red dot sights are recommended for precision.
• During break-in, some shooters have reported ammo sensitivity with light loads, but this usually self-remedies after a sufficient break-in period.

Mossberg 940 Pro Tactical Review from a LEO Perspective 

One of our readers and frequent contributors, Colonel Jim Smith, provided us with his thoughts on the Mossberg 940 Pro Tactical. Colonel Smith brings to the table decades of public safety and law enforcement experience. He specializes in firearms selection and training, use-of-force procedures, and has investigated numerous firearm-related incidents. A prolific shooter and gun owner, here is what he had to say about the 940 Pro Tactical:

I actually own and carry the Mossberg  940 Pro Tactical SPX only because my intended purchase—the basic 940 Pro Tactical—was on backorder. Except for a few extra features, they are the same weapon. Daily, the Mossberg 940 Pro Tactical sits beside me in the rack of my patrol vehicle. The 5.56 mm rifle is in second position. 

Why a shotgun rather than a semi-automatic rifle? Most law enforcement and home defense shootings occur at a range of less than 15 yards. At close range, a shotgun is a devastating weapon, usually requiring only one hit to disable a threat. With seven rounds from the Mossberg 940 Pro Tactical, one can be assured of stopping multiple threats. On the SPX model, additional shells are accessible on the standard Vang Comp® 6-Shotshell Carrier Card with its hook-and-loop card attachment system on the receiver. This inexpensive feature can easily be added to the 940 Pro Tactical allowing for quick reloading. Thirteen rounds from a shotgun should stop almost any threat.

The enlarged and beveled loading port accommodates quad loading, and the oversized charging bolt makes chambering a round simple. When reloading, you can see the bright orange shell follower indicating an empty magazine. The Mossberg traditional safety is easily accessible and allows visual confirmation of the safety’s position.

The weapon comes equipped for direct mounting of micro dots (RMSc footprint). Included are adapter plates for mounting RMR, Docter-Noblex, and Leupold accessories. If other optics are desired, the receiver is also drilled and tapped. On the SPX, the rear ghost-ring / front fiber optic sights with low-profile protective wings provide an excellent option for those who do not desire optics. 

For optimal visibility, the front sight has multiple color inserts allowing the shooter to decide which best contrasts to their background environment. With this excellent sighting system, some shooters may forego optics. In fact, if the only application for the Mossberg 940 Pro Tactical is home defense, optics are not needed with this sighting system. 

The optics-ready receiver allowed the simple mounting of a Trijicon RMR® optic. I selected a 7.0 MOA green dot which best matches my environment. The adjustment of the optic to cowitness the sights was straightforward. 

The M-Lok forend provides an excellent platform for slings, lights, and other accessories. Because I already had a generic mount on hand, I used it to install a Streamlight TLR – 1 tactical light. While the Trijicon optic provides excellent sighting under low light conditions, a tactical light provides the ability to identify a target, dazzle and disorient them with bright light, while engaging the threat if necessary. 

This shotgun comes with a variety of buttstock inserts allowing for individual adjustments to the shooter. The recoil is stout when shooting “hot” buckshot or slug loads, but is manageable and comparative to other shotguns. Shooting inertially operated tactical shotguns can prove challenging with the substantial recoil experienced from hot loads, but this is not an issue with the gas-operated Mossberg 940 Pro Tactical. The recovery time to go “back on target out of recoil” was short, and muzzle flip was not an issue. 

At the range, 2.75” Federal OO buckshot with FLITECONTROL wad produced patterns of less than 3” when fired at 15 yards. Even low-brass birdshot fed with no problems. Many tactical shotguns I have used would not reliably feed anything but high-brass shotshells. At 15 yards, the Mossberg 940 Pro Tactical also printed Federal Truball Rifled Slugs in a three-shot touching group. I also tried a variety of other shotshells, and the Mossberg 940 Pro Tactical shotgun digested them with no issues. Cleaning the weapon is simple and easy and should be done after every 500 rounds.

For home defense I recommend #4 birdshot to lessen the risk of overpenetration. At close range, these rounds are vicious to virtually any threat. 

This weapon is an excellent option for a tactical shotgun at a competitive price with some features not available on other similar, but much higher-priced, firearms. However, this is not a “first-time” purchase shotgun for an inexperienced shooter. Like any other tactical shotgun, manipulating the Mossberg 940 Pro Tactical takes practice, especially in the confines of a structure. 

My life may depend upon this weapon, but I am confident that the Mossberg 940 Pro Tactical will perform when I need it the most.

Mossberg 940 Pro Tactical vs. Alternatives: How It Stacks Up

Tactical shotguns are very popular, and thus there are numerous manufacturers offering them. We asked Colonel Smith for his take on the available options, and here’s what he had to say:

I have the Benelli Super 90 and M4, and the Remington 870. Since semi-automatic shotguns allow faster recovery for follow-up shots if needed, I prefer them over pump shotguns such as the Remington 870. The Benelli Super 90 is a good shotgun, but the perceived recoil is more substantial. Further, the Benelli’s sighting system is not as adaptable as is the Mossberg 940 Pro Tactical SPX with its interchangeable front fiber optic sights. The Benelli M4 with its collapsible stock seems unbalanced to me. It tends to dip forward, and its lighter weight makes the perceived recoil more uncomfortable. The Mossberg 940 Pro Tactical has none of these issues.

For a side-by-side comparison, see below the most popular lineup in the tactical shotgun category:
