The Mossberg JM Pro 930 is a popular semi-automatic shotgun favored by many, particularly in the competitive shooting and home defense arenas. This comprehensive review delves into its features, performance, and overall value, helping you determine if this shotgun is the right fit for your needs.
What Makes the Mossberg JM Pro 930 Stand Out?
The JM Pro 930 distinguishes itself through several key features designed for reliability and speed:
- Gas-Operated System: Unlike inertia-driven systems, the gas-operated design ensures consistent cycling, even with lighter loads or less-than-perfect shells. This reliability is crucial in high-pressure situations.
- Positive Extractor: The strong extractor consistently pulls spent shells from the chamber, minimizing malfunctions. This is a significant improvement over some other semi-auto shotguns.
- Adjustable Gas System: The adjustable gas system allows you to fine-tune the gun's operation based on the type of ammunition used. This ensures optimal performance across different shell weights and loads.
- Speed Feed System: The included SpeedFeed stock provides a quicker and smoother reloading process, a critical advantage in competitive shooting or self-defense scenarios. While not mandatory, this feature significantly contributes to the shotgun's rapid deployment capabilities.
- Durable Construction: Mossberg is known for its robust construction, and the JM Pro 930 is no exception. It's built to withstand the rigors of regular use and demanding conditions.
Performance and Handling: On the Range and Beyond
The Mossberg JM Pro 930 excels on the range, demonstrating consistent reliability and accuracy. The adjustable gas system allows shooters to tailor the gun's performance to their specific ammunition, optimizing cycling and reducing recoil. The SpeedFeed stock, while adding some weight, does indeed improve reload speed.
However, some users report a noticeable recoil, particularly with heavier loads. This isn't unexpected for a 12-gauge shotgun, but it's worth noting for those sensitive to recoil. The weight of the shotgun, while contributing to stability, might be considered cumbersome by some shooters.
Common Issues and Considerations
While generally reliable, several minor issues have been reported by users:
- Magazine Tube Capacity: Some shooters might find the magazine tube capacity insufficient for certain applications.
- Initial Break-in Period: Like any new firearm, the JM Pro 930 may require a break-in period to reach peak performance.
- Maintenance: Regular cleaning and lubrication are crucial for maintaining optimal performance and longevity.
JM Pro 930 vs. Competitors: Finding the Right Fit
The Mossberg JM Pro 930 competes with other high-performance semi-automatic shotguns, such as the Benelli M2 and the Beretta 1301. While all three are excellent shotguns, the JM Pro 930 often boasts a lower price point, making it a more accessible option for many shooters. The choice ultimately depends on individual preferences, budget, and intended use.
Conclusion: Is the Mossberg JM Pro 930 Right for You?
The Mossberg JM Pro 930 is a solid, reliable, and reasonably priced semi-automatic shotgun suitable for a range of applications, from competitive shooting to home defense. Its robust construction, adjustable gas system, and SpeedFeed stock contribute to its overall effectiveness. However, potential buyers should consider the reported recoil and potential need for a break-in period before making a purchase. Weighing the pros and cons against your specific needs will help you determine if the JM Pro 930 is the right choice for you.
