Why the Mossberg 500 Side Saddle is Necessary
From my experience, the Mossberg 500 Side Saddle is an essential upgrade for anyone serious about their shotgun’s readiness and convenience. Having extra shells right on the side of the receiver means I don’t have to fumble through a pouch or pocket when I need to reload quickly. This immediate access can make all the difference in high-pressure situations where every second counts.
Additionally, the side saddle keeps my shotgun organized and balanced. Instead of carrying loose shells or an extra belt, everything I need is mounted neatly in one place. This setup not only saves time but also reduces the chance of losing shells or getting tangled up during movement. For me, it’s about efficiency and reliability—two things I can’t compromise when handling my Mossberg 500.
My Buying Guide on ‘Mossberg 500 Side Saddle’
When I first decided to get a Mossberg 500 Side Saddle, I wanted to make sure I chose the right one to fit my needs. If you’re like me, you want something reliable, practical, and easy to use. Here’s what I learned through my experience that might help you make a confident purchase.
Understanding What a Mossberg 500 Side Saddle Is
Before buying, I made sure I understood that a side saddle is an accessory mounted on the side of the shotgun’s receiver. It holds extra shotgun shells, giving quick access for faster reloads. This is especially useful if you’re in a defensive situation or out in the field hunting.
Compatibility with Your Mossberg 500 Model
One of the first things I checked was whether the side saddle fits my specific Mossberg 500 model. Not all side saddles are universal, so verifying compatibility is crucial. Some are designed only for particular barrel lengths or receiver types, so I read product descriptions carefully or contacted sellers to confirm.
Material and Build Quality
I wanted a side saddle that would last and withstand regular use. Most are made from aluminum or polymer. Aluminum models tend to be more durable but slightly heavier, while polymer ones are lightweight and resistant to corrosion. I chose aluminum for its sturdiness, but if weight is a concern for you, polymer might be better.
Capacity: How Many Shells Does It Hold?
Side saddles come in different capacities, usually holding between 4 to 8 shells. I considered how many extra shells I wanted on hand without adding too much bulk to my shotgun. For me, a 6-shell capacity was the perfect balance.
Ease of Installation and Removal
I looked for a side saddle that was easy to install without special tools. Most models mount using existing screw holes on the receiver, which is convenient. I also liked having the option to remove it quickly if needed. Reading user reviews helped me find models praised for simple installation.
Shell Size Compatibility
Since shotgun shells come in various lengths (2 ¾”, 3″, 3 ½”), I made sure the side saddle could hold the shell size I use most. Some saddles are adjustable or made specifically for certain shell lengths. This ensures shells fit snugly and don’t fall out.
Price and Brand Reputation
Price was a factor, but I didn’t want to compromise quality. I researched brands known for reliable Mossberg accessories. Sometimes spending a little more upfront saves money in the long run by avoiding cheap, fragile products.
Additional Features
Some side saddles come with features like rubber inserts for better shell retention or ambidextrous designs for left-handed shooters. I evaluated which features mattered to me to enhance usability.
Final Thoughts
Buying a Mossberg 500 Side Saddle was about balancing durability, capacity, and ease of use. By focusing on compatibility and quality, I found a side saddle that fits perfectly and improves my shooting experience. I hope my guide helps you find the right one for your needs!
