Your Available Options and Capacity

Before you start selecting a new magazine for your Mossberg 500, you must be aware that no company offers an extension for this shotgun. In fact, the Mossberg 590 (an upgraded version of the 500) is compatible with extensions, but the Mossberg 500 is not. So all you will get is either a new mag tube, mag tube, and barrel combo, or a shotgun magazine conversion kit to make it compatible with detachable box magazines. 

The next factor to consider is the capacity of the tube/mag and if you are comfortable with it. Always confirm the capacity of the tube/mag depending upon the size and gauge of the shells, along with the quality of the follower and magazine tube. 

Legal Implications

Pump action shotguns are legal in all states and do not have too many legal restraints attached to them. However, if you are modifying your shotgun, you must be aware of the federal and local state laws. 

All states allow shotguns with tube magazines having more than the standard capacity. However, in some states (like Colorado), it is decided by the overall minimum length of the mag tube which roughly translates to no more than 10 2-¾ inch shells. 

Apart from that, if you are planning on using your shotgun for waterfowl hunting, the law bans you from having more than three shells in your shotgun while hunting. People use magazine plugs to limit the capacity of a shotgun in such cases.

Easy Installation and Proper Handling

If you choose a mag tube or a detachable magazine for your shotgun, it must be easy to install and must require minimum modifications, if any. The Mossberg 500 comes standard with a five shell magazine, or a six shell magazine. Aftermarket mag tubes that hold one or two extra shells may not be very difficult to install. However, longer tubes generally come with a longer barrel as a complete kit. 

Similarly, if you want to equip your Mossberg 500 with a detachable magazine, you will have to go for a conversion kit that will require complete disassembly and the replacement of the barrel and possibly the pump. 

A good point to remember is that these modifications to the capacity of the shotgun should not impede its handling in any way for your intended purpose.

Tube vs. Magazine: How Do They Compare?

So how does a magazine compare to a shotgun tube? For one, the tube is designed to not take up a lot of space on your shotgun, making it ergonomically friendly. Because of this, the tubes can only hold so many rounds. Your average shotgun tube will typically hold anywhere between seven to nine shots.

One of the major advantages of tube magazine shotguns is that they rarely experience failure. However, their major disadvantage is their single shell reloading.

Magazines on shotguns function the same as magazines you see in pistols. Due to some importing laws, some shotgun magazines will hold up to 5 rounds. However, aftermarket magazines will have capacities of 10 rounds and can go as high as 20 rounds.

Unlike tubes, you can easily unload and add on a new magazine full of new shells and be good to go in a matter of seconds. All you need to do is apply the magazine and close the action. These are ideal in applications like home defense or shooting competitions.

Perks of Increasing Magazine Capacity

Should you choose to increase the magazine capacity of your Mossberg 500, you will experience some advantages. They are as follows:

Faster Reloading

With an increased magazine capacity, you’ll be able to reload your shotgun at a much faster speed compared to single round reloading. This is ideal in situations where you’ll need to be able to fend off multiple attackers who dare to invade your home.

In a situation where you’re trying to reload, there’s a possibility you’ll have to take your eyes off an attacker just for the sake of reloading, which can put you in a dangerous situation.

Less Carrying of Extra Ammo

For some of us, we rely on the use of side saddles and slings to carry additional rounds of ammo. This may not be the case if you consider using a magazine for multiple Mossberg 500 rounds.

However, this may depend on the capacity of your magazine. If you’re carrying a magazine that has less than ten rounds, it would be ideal to carry additional rounds in a side saddle. But, if you have a magazine that has 10 rounds or more, having additional ammo carried around will be overkill.

Aspects to Consider Before Buying

Before you make a final purchasing decision on a Mossberg 500 magazine, it’s important to know some of the aspects that will factor into it. You should utilize them to your advantage, as opposed to finding the first magazine that you see and buying it on a whim.

The last thing you want to do is buy a cheap magazine that doesn’t work properly and lose your money in the process. With that in mind, here are some things to consider before buying your next Mossberg 500 magazine:

Capacity

As mentioned before, some shotgun magazines will have a small capacity due to importation laws. However, aftermarket magazines will more than likely have higher capacities. The capacity you want is dependent on your personal needs and preferences. If you hate the idea of reloading every few rounds, then you may want to consider a magazine of a higher capacity.

Price

Some Mossberg 500 owners are on a budget. Others have money to play with. However, the price may play a huge factor in your purchasing decision. There is one thing that needs to be noted; while we don’t discourage you from finding the best price that is affordable for you, it is important to hold the overall quality of the magazine to a high standard.

Cheap, low quality and easy to fall apart accessories are low in price for a reason. So consider buying the best magazine you can afford in terms of quality. Thankfully, some of the magazines we’ve reviewed exactly fit those criteria.

Brand Name or Manufacturer

One thing that stands out in this process is the choice between a brand name magazine or getting one straight from the factory. If you go the factory replacement route, there’s always a guarantee that the magazine will fit your Mossberg 500 or 590 shotgun.

If you’re in search of a brand name, be sure to learn about them through gun forums. Some veteran gun owners often buy something based on the name alone. That’s because they’ve bought it repeatedly and have gotten them the same results each time.

Conclusion

Finding the best Mossberg 500 magazine doesn’t have to be a challenge. But if you know exactly what you’re looking for, the process will be easy. Remember to find one that fits your personal needs and preferences.

You may not need 10 rounds and that’s fine. You can always find a good tube magazine that can hold just enough rounds. Either way, if you want more rounds for your Mossberg 500, it starts with finding a reliable and working magazine.
