Buying Guide for the Mossberg 590 Side Saddle

When I decided to enhance my Mossberg 590 shotgun, I quickly realized the importance of a side saddle. This handy accessory allows for quick access to extra shells, making it a valuable addition for home defense or competitive shooting. Here’s what I learned during my search for the perfect Mossberg 590 side saddle.

Understanding the Purpose

Before diving into the options, I made sure to understand why I needed a side saddle. It serves as a shell holder that mounts directly to the receiver of my shotgun. This placement keeps my additional ammunition within reach, which is crucial during high-stress situations. I found that having my shells readily available drastically improved my reload speed.

Material and Durability

When I looked at various side saddles, material quality stood out as a key factor. Most options are made from either polymer or aluminum. I noticed that polymer side saddles tend to be lighter and more affordable, while aluminum offers increased durability. I had to consider my intended use. If I planned on heavy field use, durability was a top priority.

Capacity Options

Capacity is another critical aspect I had to consider. Side saddles typically hold anywhere from 4 to 8 shells. I reflected on my shooting habits and the scenarios in which I would use my shotgun. For home defense, I leaned toward a 6-shell capacity, while for competition, I might prefer a 4-shell design to keep the weight down.

Mounting System

The mounting system also played a significant role in my decision-making process. I wanted something that would securely attach to my shotgun without compromising its integrity. Some side saddles use screws, while others employ adhesive or quick-release systems. I favored options that allowed for easy installation and removal, ensuring I could maintain my shotgun’s original design.

Shell Retention

I learned that shell retention is essential for preventing ammunition from falling out during movement. Some side saddles feature elastic bands or molded holders. I examined the pros and cons of each method. Elastic bands offer flexibility, while molded holders provide a more secure fit. Ultimately, I prioritized a design that would keep my shells securely in place, regardless of the conditions.

Compatibility with Accessories

Another consideration was how the side saddle would interact with other accessories on my Mossberg 590. I made sure to check if the side saddle would interfere with any optics, lights, or other attachments I had. Ensuring compatibility helped me avoid any potential issues down the line.

Price Range

Finally, I took a close look at the price range for side saddles. While I found options at various price points, I realized that higher prices often reflected better materials and design. I wanted to strike a balance between cost and quality, ensuring that I was making a wise investment for my shotgun.

my journey to find the right Mossberg 590 side saddle taught me the importance of considering various factors, from material and capacity to mounting systems and shell retention. By carefully evaluating my needs and preferences, I was able to make an informed decision that enhanced my shotgun experience. With the right side saddle, I feel more prepared and confident in any situation that may arise.
