My Buying Guides on Mossberg 590 Shell Holder
When I first started looking for a Mossberg 590 shell holder, I quickly realized that not all holders are created equal. Choosing the right one can make a big difference in convenience and reliability. Here’s what I learned from my experience and what I consider important when buying one.
Compatibility with Mossberg 590
The very first thing I checked was whether the shell holder fits the Mossberg 590 model. Some holders are made specifically for the 590 or 590A1 variants, while others might be more universal. I made sure to pick one that securely attaches to my shotgun without any wobble or looseness.
Material Quality and Durability
I prefer shell holders made from high-quality materials like reinforced polymer or metal. This ensures durability, especially since I use my shotgun outdoors in various weather conditions. A sturdy shell holder won’t crack or wear out quickly, which saves me money and hassle in the long run.
Capacity and Shell Size
Shell holders come in different capacities—some hold 4 shells, others 6 or more. I evaluated how many extra shells I wanted on my shotgun for quick reloads. Also, I made sure the holder fits the shell size I use most often, whether 2¾ inch or 3 inch shells.
Ease of Installation
For me, a shell holder that’s easy to install without special tools was a big plus. Many models come with screws and mounting brackets that attach directly to the receiver or the stock. I appreciated options that included clear instructions and all necessary hardware.
Accessibility and Retention
I wanted a holder that keeps the shells secure but also allows for quick and easy access. Some holders have elastic retention bands, while others have molded slots. I found that a good balance between tight retention and smooth removal is key during fast-paced situations.
Weight and Bulk
Since I carry my Mossberg 590 for extended periods, the added weight and bulk of the shell holder mattered to me. I looked for lightweight designs that don’t interfere with handling or add unnecessary heft.
Price and Value
Finally, I compared prices and read reviews to find a shell holder that offered solid value. Sometimes paying a little more upfront meant better quality and longer lifespan, which I found worthwhile.
My Final Thoughts
Choosing the right Mossberg 590 shell holder came down to fit, durability, capacity, and ease of use. By focusing on these aspects, I found a shell holder that enhances my shooting experience and keeps extra shells handy without compromising comfort. If you’re in the market for one, consider these points to make an informed decision that suits your needs.
