When it comes to enhancing my Mossberg 590 shotgun, one accessory I can’t recommend enough is the Side Saddle. This handy device allows me to carry extra shells right on my shotgun, making it an invaluable addition for tactical situations or even just for range days. Here’s my personal guide to help you navigate the buying process for the Mossberg 590 Side Saddle.

Understanding the Side Saddle

First off, let me explain what a Side Saddle is. It’s essentially a shell carrier that mounts to the side of your shotgun, providing quick access to additional rounds. I appreciate how it keeps my ammo readily available without the need for external pouches or bags.

Compatibility

Before I make a purchase, I always double-check compatibility. The Mossberg 590 Side Saddle is designed specifically for the 590 model, but there are variations, such as the 590A1. I recommend confirming that the Side Saddle is compatible with your specific model to avoid any fitting issues.

Material and Construction

In my experience, the durability of the Side Saddle is crucial. I prefer options that are made from high-quality materials like aluminum or polymer. These materials not only provide strength but also keep the weight down, which is important for maneuverability. I’ve found that models with a solid construction resist wear and tear, even with frequent use.

Capacity

The capacity of the Side Saddle is another important factor for me. They typically come in different configurations, such as holding 4, 6, or even 8 shells. I often choose a model that fits my needs without being overly cumbersome. For home defense, I typically go for a 6-shell carrier, as it provides a good balance of extra ammunition without adding too much bulk.

Mounting Options

I appreciate the different mounting options available for the Side Saddle. Some models utilize screws for a permanent attachment, while others use adhesive or Velcro, allowing for easy removal. I personally prefer the screw-mounted options for a more secure fit, especially if I plan to use the shotgun in high-pressure situations.

Price and Brand

When considering price, I’ve found that quality often correlates with cost. While I’m always on the lookout for good deals, I also recognize that investing in a reputable brand can save me money in the long run. Brands like Mesa Tactical and TacStar have served me well, and I trust their products to perform reliably.

Installation

The ease of installation is another thing I look for. I like to be able to install accessories without needing a gunsmith. Most Side Saddles come with all the necessary hardware and instructions. I appreciate models that allow for a straightforward installation process, so I can get back to enjoying my shotgun sooner.

Customer Reviews

Lastly, I always take the time to read customer reviews before making a final decision. Hearing about other users’ experiences helps me gauge the pros and cons of a particular model. I look for feedback on durability, ease of use, and overall satisfaction, which can provide insights beyond the product description.

my experience with the Mossberg 590 Side Saddle has been overwhelmingly positive. By considering compatibility, material, capacity, mounting options, price, installation, and customer reviews, I feel more confident in my purchase decisions. If you’re looking to enhance your Mossberg 590, I highly recommend adding a Side Saddle to your setup. It’s been a game-changer for me!
