Mossberg 590 Side Saddle Buying Guide

Understanding the Side Saddle

When I first heard about the Mossberg 590 Side Saddle, I was intrigued by the concept of adding extra ammunition storage directly to my shotgun. The Side Saddle is essentially a shell holder that attaches to the side of the Mossberg 590, allowing me to carry additional rounds conveniently. This feature is particularly useful for home defense or competitive shooting, where quick access to ammunition can make all the difference.

Types of Shell Holders

In my experience, there are various types of shell holders available for the Mossberg 590. Some are made of plastic, while others are crafted from aluminum. I found that the material affects both the weight and durability of the Side Saddle. Plastic options are often lighter, while aluminum tends to be more robust. I had to consider what would work best for my needs and how ruggedly I would use the shotgun.

Capacity Considerations

One of the first things I considered was the capacity of the Side Saddle. I noticed that they typically come in configurations that hold six or eight shells. The choice between these options really depends on how much ammunition I want to have readily available. For my uses, having more shells on hand gives me peace of mind, but I also need to balance that with the overall weight and bulkiness of the setup.

Attachment Method

When I was looking at different Side Saddles, I paid close attention to how they attach to the shotgun. Some models use adhesive backing, while others employ screws or a combination of both. I personally prefer a secure attachment method that I know won’t come loose during use. It’s important for me to ensure that the Side Saddle remains firmly in place, especially during high-stress situations.

Installation Process

The installation of the Side Saddle is something I wanted to be straightforward. I appreciate products that come with clear instructions and all the necessary hardware included. I found that some models require drilling into the shotgun, while others simply clamp onto the frame. I opted for a model that was easy to install without permanent modifications to my firearm.

Accessibility and Ergonomics

Accessibility is crucial for me when it comes to a Side Saddle. I looked for designs that allow for quick and easy access to shells without fumbling. The positioning of the shell holders should be intuitive, so I can grab a shell effortlessly. Ergonomics play a big role here; I wanted a setup that feels natural when I’m in a shooting stance.

Finish and Aesthetics

I also considered the finish and overall aesthetics of the Side Saddle. Many models come in various colors and finishes that can complement my shotgun. I appreciate a sleek look that doesn’t detract from the firearm’s appearance. A good finish can also help prevent corrosion and wear over time, which is an added benefit.

Price vs. Quality

Finally, I had to weigh the price against the quality of the Side Saddle. While I didn’t want to break the bank, I also understood that a cheaper product might compromise on durability or functionality. I looked for a balance that offered good value for the features I needed, ensuring that I wouldn’t have to replace it frequently.

Final Thoughts

In my journey of choosing a Mossberg 590 Side Saddle, I learned that there are many factors to consider. Each element, from material to capacity and installation, plays a significant role in how well the Side Saddle meets my needs. By taking the time to evaluate these aspects, I felt more confident in making a choice that enhanced my shotgun’s functionality and my overall shooting experience.
