Buying Guide for Mossberg 590 Shell Holder

Understanding the Purpose of a Mossberg 590 Shell Holder

When I first looked into getting a shell holder for my Mossberg 590, I realized how essential it is for quick access to extra shells. A shell holder keeps your shotgun shells organized and within easy reach, which is crucial whether you’re in the field, at the range, or in a self-defense situation. Knowing this helped me focus on finding a holder that suits my specific needs.

Types of Shell Holders Available

There are several types of shell holders that fit the Mossberg 590, including side saddle holders, stock-mounted holders, and belt-mounted carriers. I had to consider where I wanted to carry my shells. Side saddles attach directly to the receiver, offering quick reloads without adding bulk elsewhere. Stock-mounted holders keep the shells on the buttstock, which is convenient but might affect comfort. Belt-mounted holders give flexibility but require an additional attachment point.

Material and Durability

I paid close attention to the materials used in the shell holder. Most are made from polymer, leather, or nylon. Polymer holders tend to be very durable and weather-resistant, which suits outdoor use. Leather looks great and breaks in nicely but can require maintenance. Nylon options are often lightweight and flexible but might wear out faster. Considering how and where I planned to use my shotgun helped me prioritize durability.

Capacity and Compatibility

Capacity was important to me because I wanted to carry enough shells without making the shotgun too heavy or cumbersome. Most holders come in capacities ranging from 4 to 8 shells. I also made sure the holder was compatible with 12-gauge shells, as that is what my Mossberg 590 uses. Some holders specify their shell size compatibility, so I checked these details carefully.

Ease of Installation and Use

A simple installation process was a big plus. I looked for holders that required minimal tools or could be attached quickly. Ease of use during reloading was equally important—I wanted the shells to stay secure during movement but also be easy to grab when needed. Reviews and user feedback helped me gauge this aspect before deciding.

Comfort and Weight Considerations

Since I carry my shotgun for extended periods, I considered how the shell holder would affect overall weight and balance. Some holders add noticeable bulk, which can tire your shoulder or alter handling. I aimed for a lightweight option that distributed weight evenly to maintain comfort during use.

Price and Value

Finally, I balanced cost with features and quality. While shell holders aren’t typically expensive, I avoided the cheapest options that might compromise durability. Instead, I focused on finding a good value that offered reliable performance without overspending.

Final Thoughts

Buying a Mossberg 590 shell holder is about matching your specific needs with the right type, material, capacity, and ease of use. By considering these factors, I was able to find a shell holder that enhanced my shotgun’s functionality and improved my overall shooting experience.
