Perks of Having Additional Magazines

If you are using a magazine fed rifle, like the M1A, having some extra magazines at hand is always helpful. Let's consider some situations to help you better understand. Consider yourself plinking at the range, with only a couple of mags. You’ll have to spend more time reloading than shooting. Having some extra magazines will let you make the most out of your practice sessions.

Similarly, if you are hunting varmints or hogs, it is obvious that you’ll be taking quick follow up shots. Having additional magazines will keep you ready and engaged.

People tend to drop the magazines and stomp over them at the range, making them prone to malfunction. So it is always a better idea to keep a separate set of magazines for precision uses like self-defense, competitions, or for situations where you cannot afford a malfunction.

Similarly, if you get caught up in a self-defense situation, you might end up burning ammunition fast, especially if there are multiple hostiles. Having some extra mags on hand will allow you to hold the situation until help arrives.

Magazines are also an ingenious way of keeping ammunition organized. Plus, they are also easy to handle and store. Finally, buying extra magazines for your M1A is not a very costly affair. So having some extra ones is the right decision, logically and economically.

What Makes Great M1A Magazines?

An ideal M1A magazine must possess several qualities. The very first is durability. A good magazine must be durable and tough enough to withstand fatigue and pressure. Magazines are quite prone to being dropped, kicked, or stomped, even if done accidentally. Having a high-quality magazine ensures reliable operation and reduces replacement costs.

The next quality is the texture. A good M1A magazine should have an anti-slip texture so it is easy to hold and change, as you might end up in a situation where your hands get sweaty or wet.

Another important aspect of the magazine is its follower. A good magazine must have a self-adjusting, anti-tilt follower, so it doesn’t jam. Such followers level automatically to prevent a feed malfunction. Followers can either be polymer or metal. But the material really doesn’t matter as long as it is self-adjusting.

One more thing to consider here is that the magazine should be properly sized to easily fit the mag well. Plus, it should drop freely when released, without the need for thumping or pulling it out of the rifle. The best bet is to purchase magazines specially designed for the M1A, like the ones included in this review.

Lastly, a magazine for your M1A must be easy to clean. Just like the rifle, magazines also collect grime and dust, so they need to be cleaned regularly. Having an easily removable floor plate to open up the magazine will come in handy while cleaning, so keep an eye out for that.
