Mossberg 590 Shell Holder Buying Guide
Introduction to the Mossberg 590 Shell Holder
When I first started looking into upgrading my Mossberg 590, I quickly realized the importance of having a reliable shell holder. This handy accessory allows me to keep extra shells within easy reach, making reloading much smoother during range sessions or when I’m out in the field.
Types of Shell Holders
I discovered that there are different types of shell holders available. Some attach directly to the shotgun, while others come as standalone pouches or sleeves. I found that choosing the right type depends on my usage and preference for convenience versus accessibility.
Material Considerations
The material of the shell holder plays a significant role in its durability and functionality. I noticed that options range from nylon to elastic and even leather. I preferred a material that can withstand rough conditions while ensuring my shells are secure and protected.
Capacity and Size
When I was selecting a shell holder, I had to consider the capacity I needed. Some holders accommodate just a few shells, while others can carry a full box. I realized that the size and weight of the holder also matter, especially if I plan to carry it for extended periods.
Attachment Methods
Attachment methods were another critical factor for me. I found options that use Velcro, snaps, or even MOLLE systems for mounting. I needed to think about how I wanted to carry the holder—whether on my belt, the shotgun itself, or a tactical vest.
Ease of Access
I wanted a shell holder that allows for quick and easy access to my shells. I explored designs that provided an open top for rapid retrieval versus those that fully enclose the shells. This aspect was crucial in ensuring I could reload swiftly when necessary.
Price Range
As I compared different shell holders, the price varied significantly. I learned that higher prices do not always guarantee better quality. It was essential for me to find a balance between affordability and the features I desired.
Brand Reputation
While I didn’t want to focus on specific brands, I understood the importance of selecting a reputable manufacturer. I read reviews and gathered feedback from other Mossberg 590 users to gauge the reliability of various options.
