My Buying Guides on Mossberg 500 Side Saddle
When I first decided to enhance my Mossberg 500 shotgun with a side saddle, I wanted to make sure I chose the right one that fits my needs perfectly. Here’s what I learned and what I think you should consider when buying a Mossberg 500 side saddle.
Understanding What a Side Saddle Is
A side saddle is a shell carrier that attaches to the side of your shotgun’s receiver. It holds extra shotgun shells, giving you quick access during shooting or tactical situations. For me, having additional rounds right on the gun improved my reload speed and overall convenience.
Compatibility with Mossberg 500
Not all side saddles fit every shotgun model. When I shopped around, I made sure the side saddle was specifically designed for the Mossberg 500 or was at least compatible with it. Some models fit only specific variants (like 12 gauge), so checking this is crucial before purchasing.
Material and Build Quality
I preferred a side saddle made from durable materials like aluminum or high-strength polymer. This ensures it can withstand regular use and rough conditions without breaking or bending. Metal saddles tend to be heavier but more rugged, while polymer options are lighter but still sturdy.
Capacity and Shell Size
Side saddles come in different capacities — usually holding between 4 to 6 shells. I chose one that held 5 shells because it balanced extra ammo and weight well for me. Also, consider the shell size (2¾ inch, 3 inch, or 3½ inch Magnum shells) to match your ammunition.
Ease of Installation
I wanted something that I could install myself without special tools. Most Mossberg 500 side saddles come with mounting screws and instructions. Some snap on easily, while others require a bit more effort. Look for one with clear instructions and included hardware.
Retention and Security of Shells
Having shells fall out during movement is frustrating. I tested a few saddles to see how well they held the shells. Some use spring tension or rubber loops to keep shells secure. Choose a model that firmly holds shells but still allows quick removal.
Finish and Appearance
While performance was my priority, I also considered the finish to match my shotgun’s look. Most side saddles come in matte black or anodized finishes that resist corrosion and wear. Pick one that complements your shotgun’s aesthetics.
Price and Brand Reputation
Prices vary depending on materials and features. I found that well-known brands like Mesa Tactical or ATI offered reliable products worth the investment. Avoid very cheap options that might compromise quality or durability.
Additional Features
Some side saddles offer extra perks like integrated tools or compatibility with other accessories. I looked for any additional features that might benefit me in the field or range.
Final Thoughts
Buying a Mossberg 500 side saddle is about balancing capacity, durability, and ease of use. From my experience, choosing a quality, compatible saddle made a noticeable difference in my shotgun’s functionality. Take your time to research, read reviews, and consider your shooting needs before making a decision.
