Your Guide to Finding the Best Side Saddle for Your Mossberg 590
The Importance of a Side Saddle
A side saddle is a must-have accessory for your Mossberg 590 shotgun. It attaches to the receiver of your shotgun and holds extra shells. This means you can reload faster in a pinch. It’s like having an extra magazine ready to go!
Key Features to Look For
Shell Capacity
Side saddles come with different shell capacities. Most hold three to six extra shells. Think about how many extra shells you want to carry. More shells mean a bulkier side saddle, so find a balance that works for you.
Material and Durability
The best side saddles are made from tough materials. They need to withstand bumps and drops. Look for strong polymers or metal. These materials keep your shells secure and your side saddle lasting a long time.
Ease of Installation
You don’t want a complicated installation. A good side saddle attaches easily to your Mossberg 590. It should fit snugly without needing special tools. This saves you time and frustration.
Grip and Texture
The surface of the side saddle should offer a good grip. This helps you grab shells quickly, even with gloves on. Some have textured surfaces that improve your hold.
Fit and Compatibility
Make sure the side saddle is specifically designed for the Mossberg 590. Different shotgun models have different receiver shapes. A proper fit prevents the side saddle from moving or rattling.
Important Materials

- Aluminum: Some side saddles use aluminum. It’s strong and light, but can be more expensive.

Factors That Improve or Reduce Quality
Improving Quality
