Equip Your Mossberg 590: The Essential Side Saddle Buying Guide
So, you’ve got a Mossberg 590 shotgun. That’s a solid choice! Now, you’re thinking about adding a side saddle. A side saddle is a cool attachment that holds extra shotgun shells right on your firearm. It makes reloading faster and keeps you ready for action. Let’s break down what to look for when you buy one.
Key Features to Look For
When picking out a side saddle for your Mossberg 590, think about these important things:
- Shell Capacity: How many extra shells do you want to carry? Most side saddles hold 4 to 8 shells. More shells mean fewer trips to your ammo pouch, but it can also make the shotgun a bit heavier.
- Mounting System: How does the side saddle attach to your shotgun? Most use screws that go into pre-drilled holes on the receiver. Some might use Velcro or clamps. A secure mount is super important. You don’t want your shells bouncing around!
- Shell Retention: How well does it hold the shells? You want a side saddle that grips your shells firmly so they don’t fall out when you move. But, you also need to be able to grab them quickly when you need them.
- Material: What is it made of? We’ll talk more about this next.
- Ease of Installation: Can you put it on yourself, or do you need special tools? Most are pretty easy to install.
Important Materials
The material of your side saddle affects its strength and how long it lasts.
- Polymer (Plastic): Many side saddles are made of strong polymer. This material is lightweight and doesn’t rust. It’s a popular choice because it’s tough and affordable.
- Aluminum: Some premium side saddles use aluminum. Aluminum is very strong and durable. It’s a bit heavier than polymer but can withstand rough use.
- Rubber: The shell loops themselves are often made of rubber or a similar flexible material. This helps them grip the shells tightly.
Factors That Improve or Reduce Quality
What makes a side saddle great? And what makes it not so great?
-
Good Quality:
- Solid Construction: The side saddle feels sturdy and well-made. No wobbly parts.
- Precise Fit: It fits your Mossberg 590 perfectly without any gaps or forcing.
- Secure Shell Retention: Shells stay put but are easy to remove.
- Durable Materials: The material holds up to use and doesn’t crack or break easily.
-
Poor Quality:
- Loose Fit: It doesn’t attach tightly to your shotgun.
- Shells Fall Out: The shell loops are too loose.
- Cheap Materials: The plastic cracks or the metal bends easily.
- Difficult Installation: It’s a struggle to get it on your shotgun.
User Experience and Use Cases
How do people use side saddles, and what’s it like to have one?
- Home Defense: For your Mossberg 590 at home, a side saddle means you have extra rounds ready if you need them. You can quickly reload if you fire your initial shots.
- Tactical Shooting: If you participate in shooting sports or training, a side saddle helps you reload faster during competitions or drills. This can give you an edge.
- Hunting: While less common for hunting, some hunters might use a side saddle for specific situations where extra shots might be needed.
- Overall Experience: Most users find that a good side saddle makes reloading much smoother and faster. It keeps your spare shells organized and within easy reach. It adds a bit of weight and bulk, but most agree the benefit of quick reloads is worth it.
