Hey guys, let's dive deep into a shotgun that's become a favorite among competitive shooters and home defense enthusiasts alike: the Mossberg 940 JM Pro. This isn't just any shotgun; it's a collaboration with the legendary Jerry Miculek, a name synonymous with speed and precision in the shooting world. We're going to explore everything from its design and features to its performance and what makes it stand out in a crowded market. If you're considering a new shotgun, especially for action shooting or personal protection, you'll want to pay close attention. I'll cover the details from its reliability, to its ease of use and modifications, so buckle up and let's get started!

The Genesis of a Champion: Design and Development

The Mossberg 940 JM Pro wasn't just slapped together; it was meticulously crafted with input from Jerry Miculek himself. This collaboration resulted in a shotgun designed to excel in competitive shooting, particularly in sports like 3-Gun. The goal was simple: create a shotgun that's fast, reliable, and easy to handle. And boy, did they succeed! From the outset, the design focused on several key areas, including enhanced ergonomics, improved cycling, and increased capacity. They knew that if it was good enough for Miculek, it would be good enough for the rest of us. The 940 JM Pro builds upon the proven platform of the Mossberg 930, addressing some of the common issues and introducing upgrades that make it a serious contender. The most notable changes include improvements to the gas system, a redesigned forend, and a host of user-friendly features.

One of the main focuses of the development was to make the 940 JM Pro as reliable as possible. The gas system was revamped to handle a wider variety of ammunition, reducing the chances of malfunctions. This is critical in competitive shooting, where every split-second counts, and a jam can mean the difference between winning and losing. Mossberg also paid attention to the little things, like the loading port, making it wider and easier to load quickly. The controls were also tweaked, improving the overall user experience. The stock and forend were designed to enhance handling and provide a comfortable shooting experience, even during extended periods of use. The result is a shotgun that feels good in your hands and performs flawlessly under pressure. If you're in the market for a shotgun that is going to be your go-to, this is the one! This is the shotgun for you to practice and get better.

Key Features: What Sets the 940 JM Pro Apart

Okay, so what makes the Mossberg 940 JM Pro special? Let's break down some of its key features:

  • Enhanced Gas System: The gas system is the heart of the 940 JM Pro, and it's been engineered for reliability. It's designed to cycle a wide range of ammunition, from light target loads to heavy magnum rounds, without issue. This means fewer malfunctions and more time spent shooting. This is particularly important for competitions where the shooter could be switching loads depending on the stage design.
  • Extended Magazine Tube: The extended magazine tube is a must-have for competitive shooting. It significantly increases the shotgun's capacity, allowing you to get more rounds downrange before reloading. The 940 JM Pro typically comes with an extended tube, giving you a serious advantage in events like 3-Gun, where the ability to deliver a high volume of fire is key. There are some states or cities that do not allow extended magazine tubes. Be sure to understand your local and state laws.
  • User-Friendly Controls: The controls of the 940 JM Pro are designed for ease of use and fast manipulation. The oversized bolt handle and enlarged bolt release make it easier to operate under stress, and the safety is conveniently located for quick access. These features can make all the difference when you're under pressure. If you are going to use this shotgun in a competition, you will need to learn to get used to the controls.
  • Adjustable Stock: The stock is adjustable for length of pull, allowing you to customize the fit for your body type and shooting style. This is crucial for achieving a comfortable and consistent shooting stance. A proper fit will improve accuracy and reduce felt recoil, leading to a more enjoyable shooting experience. This adjustability is a game-changer when it comes to being able to shoot all day long.
  • Fiber Optic Front Sight: The fiber optic front sight is bright and easy to see, even in low-light conditions. This enhances target acquisition and allows you to get on target quickly. This is a real advantage in any shooting scenario.
  • Ported Barrel: The ported barrel reduces muzzle rise, allowing for faster follow-up shots. This is another feature that enhances the 940 JM Pro's suitability for competitive shooting.

Performance: Reliability and Handling

Now, let's talk about performance. The Mossberg 940 JM Pro is known for its reliability and smooth handling. The gas system does an excellent job of cycling a variety of loads, and the enlarged controls make it easy to operate under pressure. The felt recoil is also manageable, thanks to the design of the stock and the weight of the shotgun. In terms of handling, the 940 JM Pro feels balanced and comfortable in the hands. The forend is designed to provide a secure grip, and the overall ergonomics are well-thought-out. It points naturally and is easy to swing on target. Whether you're shooting clays, competing in 3-Gun, or using it for home defense, the 940 JM Pro delivers consistent performance.

One of the aspects of the 940 JM Pro's performance that I personally appreciate is its speed. It's designed for quick follow-up shots, and the ported barrel helps to minimize muzzle rise. This allows you to stay on target and get those follow-up shots off faster. The smooth cycling action and the well-placed controls contribute to this speed. I can get through a course of fire faster with this gun than with others that I have tried.

Modifications and Customization

One of the great things about the Mossberg 940 JM Pro is the wealth of customization options available. There are a variety of aftermarket parts and accessories that can enhance its performance or tailor its appearance to your liking. Here are some of the most popular modifications:

  • Upgraded Trigger: An upgraded trigger can significantly improve the shotgun's feel and performance. Aftermarket triggers offer a crisper break and a shorter reset, which can translate to faster and more accurate shooting.
  • Enhanced Sights: While the factory sights are already good, there are even better options available. You can upgrade to a red dot sight or a different style of iron sights for enhanced target acquisition.
  • Magazine Tube Extensions: While the JM Pro already comes with an extended tube, you can further increase the capacity with aftermarket extensions, although you should always be aware of local laws and regulations.
  • Forend and Stock Upgrades: If you want to change the ergonomics or the look of your shotgun, you can find various aftermarket forends and stocks. These can be made from different materials, such as wood or synthetic, and can offer improved grip or adjustability.
  • Cerakote or Custom Finishes: If you're feeling creative, you can have your shotgun Cerakoted or custom-finished. This will give it a unique look and can also improve its durability.

Remember, guys, when modifying your shotgun, always prioritize safety and ensure that any modifications you make are legal and safe to use.
