What to Watch For When Buying Side Saddles For Your Mossberg 500

A side saddle might seem like a simple shotgun accessory without a lot of variation. However, there are still a few things that it pays to keep an eye out for when shopping for one. They are not all made equally. Considering the fact that a side saddle’s job is to hold extra ammo, it is important to choose one that is durable, reliable, and made from high-quality materials.

Paying attention to the design and how it might affect your shooting style is another important consideration to keep in mind. That being said, with a little bit of prior research, finding the ideal side saddle for your Mossberg 500 won’t be too big of a challenge. The tips and info below are a good place to start!

Counting Capacity

Your first thought when it comes to the capacity of a side saddle might be to go with the one that holds the most extra shells. However, while the idea of carrying the maximum amount of extra ammo is sound logic, that doesn’t automatically make it the best choice for everyone. Capacities for Mossberg 500 side saddles typically range from four shells up to eight shells. These usually go up in two shell increments, but there are some odd numbered capacity side saddles out there too. 

It is important to balance side saddle capacity to the situation you plan to use it in and with your shooting style and particular Mossberg 500 model. A fully loaded eight shell capacity side saddle does add some weight and can throw off your balance even if only slightly. If you plan to participate in shooting competitions, there may be limits on side saddle capacities. Make sure to check any relevant rules before making your side saddle buying decision.

Appearance Matters

While it should come second to performance, there is nothing wrong with choosing a side saddle that you find aesthetically pleasing. There are enough options on the market for there to be plenty of variation in the design and appearance of Mossberg 500 side saddles. The most common color for side saddles is black, but it is possible to find other colors as well. Being as simple in design as they are also making side saddles easy to paint if necessary or desired.

Installation Intensity

One other consideration to keep in mind when shopping for a side saddle is the installation process. This will typically be a very simple task no matter which specific side saddle you go with, but it always pays to make sure there is nothing unexpected when it comes to installation. As long as you are looking at side saddles compatible with Mossberg 500 shotguns, you will be fine!

It is designed to give you easy access and fast reloading, no matter the application.

Bottom Line

The Lyman Side Saddle Shell Holder has proven itself as worthy of the Best Overall title. While it is designed mostly for law enforcement use, it can also be used by the everyday Mossberg owner. More specifically, if you’re using your Mossberg for home defense purposes, this is probably the side saddle you’ll want.Whether you want a 4-count or a 6-count, you’ll be satisfied with this.

If you’re on a budget, you know for sure that we’ve handpicked an excellent side saddle for you. We’ve bestowed the honor of “Best For The Money” to the Mesa Tactical SureShell Side Mount Shell Carrier. This carrier is also available in 4-count, 6-count, and 8-count.

The top of this side saddle has that ribbed look (which looks like some kind of Picatinny rail). It is definitely something that you want to install on your receiver. Speaking of installation, this is easy to install on your Mossberg 500 without ever having to rely on a professional gunsmith. If you have no gunsmithing skills whatsoever, you can breathe a sigh of relief.

The finish is a matte black finish that will blend in with your shotgun without making it look like an aesthetic disaster. So if looks matter to your Mossberg, then you won’t have to worry about this making it look ugly.

Overall, this is a side saddle that is more than what you’d expect from a run-of-the-mill kind of budget side saddle. If you’re looking for something that will give you more than what you’ll pay for, the Mesa Tactical SureShell might be your best choice.

Bottom Line

Sometimes, a good side saddle doesn’t have to be attached with screws. With that said, we present to you the best velcro side saddle on the market. This is the NcStar Universal side saddle, designed to hold your favorite 12 gauge shotgun shells.

This is a six-count side saddle that you can install on your receiver, making it one of the easiest, most accessible side saddles on the market. All you need to do is reach for a shotgun shell, load it up, and take your shot. From there, it’s rinse and repeat.

Bottom Line

For its part, the NcSTAR side saddle does a pretty good job of holding your shotgun shells together. Since it’s velcro, this will likely give all the other side saddles (Velcro or otherwise) a run for their money. For the most part, this has the ability to keep the shells snug and secure, especially when you’re firing off multiple rounds with your Mossberg 500.

If you hate the idea of using screws and want a side saddle that is easy to slap on and be good to go, then the NcSTAR might be the side saddle that’s best for you.

If you’re a fan of the TacStar brand, we have the best side saddle directly from them. More specifically, we have the Hunter’s Sidesaddle. This comes in a 4-count holder, which is ideally designed for the bird hunter or the big game hunter. You can install this on your Mossberg 500 without ever having to make any modifications to your shotgun.

It has an aluminum backplate that is rugged, durable, and will be able to handle the recoil of your shotgun. The best thing about this side saddle is not only is it available for 12 gauge Mossbergs but 20 gauge Mossbergs as well.

This also comes in two colors: Realtree Advantage and hunter black. Whether camo is your thing or not, this is a reliable side saddle to have when you’re out in the field and ready to knock down that big game target you’ve been after all season long.

Bottom Line

For a side saddle, this one is as tough as it gets. The polymer construction really does make it impervious to damage, which really impresses us. Not only that, this is probably going to be your best hunting buddy if you decide to go with this side saddle. So if you use a Mossberg 500 for the purpose of hunting big game or bird hunting and need a universal fit side saddle, the TacStar will probably be the side saddle worth investing in.

Finally, we’ll be taking a look at the best from the ATI brand. The shotshell holder has the ability to hold up to 5 12 gauge shotgun shells. This side saddle is also one tough customer because of the material it’s constructed from.

While it is polymer, it is not your average type of polymer. This is Extreme Temperature Glass Reinforced Polymer developed by DuPont. Yes, that’s the same DuPont that develops kevlar for bulletproof vests.

Most important, this is an easy to install side saddle. No need for fancy tools or gunsmithing skills. This is an ideal side saddle for the purpose of hunting, though you can certainly use this for just about any other application you want.

Bottom Line

This side saddle and the TacStar will possibly duke it out in the not so distant future when it comes to side saddles. I won’t be surprised if there’s a great debate about these two at some point down the road. But for now, if you want a side saddle that is super durable and you fancy yourself a fan of the ATI brand, then this might be the side saddle that fits your Mossberg 500 perfectly.

What is a Side Saddle and What Is It Used For?

Side saddles are used to store extra shotgun shells and are designed to stay attached to the side of your shotgun. This is a handy accessory to have when you want to keep extra shotgun rounds on you while you’re out in the field or out on the range.

In a home defense situation where multiple attackers are present, having extra shells handy can be a huge difference maker. These side saddles are often installed on the buttstock of your shotgun. Also, you can install some of these on your shotgun receiver. This will allow for easy access and fast reloading, which is definitely a plus for most applications.

How to Choose a Side Saddle

There are some features and aspects that you need to consider prior to choosing a side saddle. You need to know which one will be a more reliable side saddle compared to those that are considered cheap and low quality. To get a better idea of how to choose a side saddle that best fits you, it’s important to know what drove past buyers to choose theirs. Here are a few things that they would want you to keep an eye out for while buying a side saddle of your own:

Intent and Purpose

What is your Mossberg 500 shotgun used for? Are you a hunter? Is it for home defense? Are you a competitive shooter? No matter what your intended purpose is, you need to make sure that you’re prepared with extra shells when the situation arises that you need them.


While your side saddle is designed to give you fast reloading and less time trying to find extra shells, knowing how many you can carry is key. This is based on your personal needs and preferences.

There are some side saddles that will hold up to 4 rounds, while others will hold up to 6 or more. Once again, this will depend on your intended purpose. If you’re out in the field for a hunt, it’s best to carry one with a capacity of 4. You can get away with 6 if you like. If you’re in a competition, then finding one with a larger capacity will be essential.


Of course, the ease of installation is important when it comes to side saddles. One of the ways to install a side saddle is by screwing them on the receiver of your shotgun. There are even some side saddles that you can install on your buttstock.

These are typically the Velcro type side saddles that you can easily stick to either the stock or if you choose, the receiver. Either way, they’re both easy to install without having to rely on the services of a professional gunsmith.

How to Install a Side Saddle on Your Shotgun

Sure, it’s easy to install a side saddle on your shotgun. But you may not have any installation instructions that will come with the side saddle that you choose. So, we’ve taken the liberty of providing you with side saddle instructions of your own. Keep in mind that this will pretty much be the same instructions no matter which side saddle you choose (of course, if you chose a velcro side saddle, you may disregard this part). With that said, here’s how you install a side saddle on your shotgun:

  1. Before doing anything else, make sure that your shotgun is unloaded.

  2. Open the action and lay the shotgun down with the ejection port facing up.

  3. Remove the screw that is located inside the ejection port. You’ll need a screwdriver or a Leatherman. You will have a replacement screw that comes along with the side saddle you chose.

  4. Place the screw in the ejection port, screw it in.

  5. Pop out the pin located just near the trigger housing. You can pop it open using a long screw and tap it with the handle end of the screwdriver. The screw will pop out from the other side. Push in the replacement all the way. You should see the threads stick out. This is normal.

  6. Remove the washers located on the holes of the side saddle using an Allen wrench. What you’re doing here is separating the mounting plate from the shell compartments.

  7. Install the plate on your shotgun. Secure it properly using an Allen wrench.

  8. Add the nut and washer in the larger hole and tighten it until secure.

  9. Place the shell holders and tighten them until secure using an Allen wrench.

  10. Double check to see if the side saddle is snug and secure.

How to Reload a Shotgun Using a Side Saddle

Now here comes the fun part. There are two different techniques will show you on how you can reload a shotgun using a side saddle. This is ideal in a home defense or competition application. In order to reload a shotgun using your side saddle, you’ll need to follow these instructions for each technique. Let’s start with the first one:

Technique #1

  • You need to make sure that the shells in your side saddle are placed brass side down. As you reload, make sure the stock is tucked below your armpit.
  • Pull down a shell brass side down and quickly load it into the loading port. Push it into the magazine tube using your thumb.

Technique #2

  •  You can alternatively load the shell into the ejection port. You can do this without looking at the gun.
  • This time, the brass part of your shells should be facing up.
  • Blade your hand and point it toward you. As you’re doing this, push up the shell closest to you using your thumb. Feed the shell using the magazine tube.
  • Alternatively, you can load it via the ejection port.


Finding the best Mossberg 500 side saddle is easy if you know what you’re looking for. If you need one with 4 shells or 8, having one handy in any application is always good to have. Especially when you want to reload and get a shot off fast.

Remember, if a side saddle sticks out as one of your favorites, make sure you do more further research to ensure that you are making the right decision when it comes to choosing a great side saddle. Timing is everything when it comes to these things. So find one that will allow you easy access and will quicken your ability to reload your Mossberg 500.
