Rockwell ClassProper care of magazines should be common knowledge. Doing so as needed should be second nature. Unfortunately, not only have many shooters not been taught the hows/whys and whens of magazine care, there are many who do not even know how to disassemble one. This is particularly true of the old, ubiquitous (grunts: ubiquitous) 30-round USGI magazine. Regardless of the mag, you need to take care of it. This is a great primer on that, written by my friend Jared, one of the primary instructors at Rockwell Tactical. It first appeared over on Black Sheep Warrior. I thought it warranted ALCON distro. If you have anything to add, let’s hear it. Mad Duo Nate

MAGAZINES

by Jared of Rockwell Tactical

Magazines in the modern firearm are a part of the weapon system. Your firearm is next to useless without magazines that work. I have seen too many people spend lots of money on a gun and give no thought to spending anything on magazines. You should get the best mags you can, yet don’t get too attached to them when it’s time for them to go.

Author, putting a broken PMAG through its paces.

You should use a paint marker and mark every magazine you have. I use a simple symbol that I made up, while some of the guys on my team use their initials. That way everyone knows which ones belong to whom. You should also number every mag. If you have a problem while shooting, you just need to remember what number magazine was bad. If the same malfunction happens a few times in a row, then it most likely is the mag that is causing the malfunction.

You should mark every mag you have and be prepared to throw it out.

Most of the malfunctions you will have with your firearm are because of the magazine. If you ID a bad mag, just get rid of it. There is no need to get emotionally attached to it. Don’t try to sell it and don’t just leave it around to be picked up by someone else. I write “bad” on them, and then throw them out. You could always give them to someone you hate, but even that is a little too mean.  Pawn shops and surplus stores around military bases are notorious for selling someone’s old, worn-out mag.

 

“I have seen too many people spend lots of money on a gun and give no thought to spending anything on magazines. You should get the best mags you can, yet don’t get too attached to them when it’s time for them to go.”

 

You should check your mags as a part of your routine maintenance. Check the spring tension, making sure that it is strong no matter how many rounds are in it. The feed lips should also be checked as they tend to wear out. Load the mag 2/3 of the way, hold it with one hand and give it a few good palm strikes on the base of the mag. If a few rounds pop out, your feed lips are worn and it’s time to get rid of that mag. Also don’t forget to inspect every mag for any cracks or other damage.

With all of today’s magazines you can load them to maximum capacity. None of this 28 rounds in a 30 round mag or 9 rounds in a 10 stuff. If your mag causes you to have feeding problems by loading it all the way, get a new one. Make sure you routinely rotate your mags and don’t keep them loaded for an extended period of time. Despite those who say it is an urban legend, some magazine springs will take a set.   A relative of mine was showing me his old GI 1911. He had a loaded mag in it. Well, he hadn’t changed out the mag for a few years, and the rounds just fell out of it. The spring was so set to the same position that it didn’t move at all.  I have also experienced a few of my own mags that have taken a set.

This PMAG had been run over by a large military vehicle but still functioned!

Another thing to consider concerning the spring life is how often they are loaded and unloaded.  This is the biggest cause of springs wearing out.  So if you rotate your mags every other day, you are doing much more harm to them than good.  Today’s springs are of a better quality than those 50 years ago, and they will last longer.  Just realize that with use, comes wear.

 

“We need to start thinking of magazines like an oil filter for our vehicles.  Every 3000 to 5000 miles it’s time to get a new one.”

 

There is a difference in advice I can give between pistol and rifle magazine choices. For a pistol, with the exception of the 1911 platform, you should only use factory original mags. There are plenty of aftermarket mags, usually cheaper than the factory ones, but they are made to unknown specs. You have to ask yourself if your life is worth a few saved bucks. Stick to factory originals, but it is alright to use some of the aftermarket accessories for your magazine. I am not a big fan of the 2-round extender base plates. They are advertised as not needing a new spring and I just don’t trust that. With that said, there are a few companies that do make good, extra-power magazine springs. So if you have extenders, upgrade your springs.

Notice the cracked follower.

About the only pistol that I would trust my life with, with aftermarket mags, is the 1911. The 1911 has almost too many different aftermarket magazines to count. Some of them are very high quality (much better than the 7-round GI mags that sometimes come with the gun). During my last trip overseas, I used Wilson Combat 8 and 10-round mags. No problems with them, unlike the GI ones.

In contrast to the pistols, there are a plethora of aftermarket mags for rifles that are great to use. It seems like more types are being developed every year. Metal and polymer-based ones are both equally reliable. In my military experience, I have used the GI aluminum, steel and a few different polymer ones. All were reliable under various conditions. As long as I took the time to do regular maintenance on them, none of them gave me any more problems than normal. But don’t just trust something on reputation. If you’re going to buy the popular name brand because all your buddies are using it, you better make sure it works for you and your weapon.

A friend of mine once had his loaded Pmag run over by a big and heavy military vehicle. The base plate was broken and some of it was missing, the side window was cracked, and the follower was cracked in half.  He was going to throw it away, but I grabbed it from him for some ‘real’ torture testing. Single shot: no problem. Controlled pairs: no problem. I dumped the last 20 rounds on full auto: no problem. I was, and still am, impressed by the Pmags.  With that said, some of my teammates were issued what must have been a bad lot of Pmags.  They had nothing but problems with them and to this day refuse to use them.

Something else I have done with a few of my M4 mags is to put a little piece of skateboard grip tape along the front edge. You can get the tape for next to nothing and I have gotten scraps for free. The tape can help you to get a better grasp of the mag, which is especially important when things are wet or otherwise slippery. I have used it on both the aluminum magazines and Pmags.  Another technique is to stipple your polymer mags to give them a rougher surface.  This can be easily done.  Just go to Wal-Mart and buy yourself a $10 wood-burning tool in the craft department and you are in business.

Adding grip tape can help you to get a better grasp of the mag.

We need to start thinking of magazines like an oil filter for our vehicles.  Every 3000 to 5000 miles it’s time to get a new one.  Use that mag till it don’t work no more, then get a new one. Whatever you use, the most important thing to remember is: if you are going to trust your life to a magazine, take it to the range and use it. Make sure it works flawlessly for you.

I would strongly suggest making every attempt to destroy the magazine ASAP! In the military, I saw too many armorers take a broken magazine then throw it in a pile with good ones only to pass that jacked up magazine on to the next new guy going down range (even if you marked it with a large B or BAD on the side). Hopefully this practice has changed over the last few years since I got out, but I doubt it.

This piece is great, but it is difficult to apply to military personnel who simply cannot throw out a used magazine. I cannot imagine a PV3 running up to their team leader and saying: hey, I shot 10,000 rounds through this mag, can I get a new one? Undoubtedly, the response would be: so what, put it back in your pouch and move out. Obviously this is a culture issue and probably varies between units, but it is one that I do not foresee changing anytime soon.

I agree completely. It's my rule to always completely smash any mags that I don't trust. I too have seen mags turned in only to see someone recycle them and say "it was probably just a dirty rifle".

I however do not agree with the idea of filling up a standard issued mag to 30rounds. I only load 28 and expect that from others as well. Why- the first reason is simply because the mag seats MUCH more easily on a closed bolt (such as clearing a stoppage and dumping the mag, then loading on a closed bolt). The second reason is that I have found through experience that the small amount of play left in the spring when loaded with 28 rounds makes it more forgiving when dirty. The mag has less pressure on the feed lips and the top round, so if some grit has gotten in there (as it inevitably does), that top round will chamber cleanly almost always with 28 rounds, rather than fighting the grit as it's stripped off the top by the bolt when 30 are in place.

This second reason does not apply to modern HK mags or PMAGs, only the standard issue mags.

To add to this – many years ago as an armorer, I found that all the Colt Mfg. issue 20 rd magazines were absolutely junk – only the magazines marked as manufactured by a Parson's Kansas contractor were any good. The flaws were not obvious, so modification was not called for. I threw everyone of the Colt magazines in a foot locker marked "FOR TRAINING ONLY"; and kept the good ones back for deployment.

Our troops got some good remedial action training with those crappy Colt magazines! They sure knew about every failure in the book after using them!

As long as the body is good, I don't see why you would throw it out. I'd replace the spring, along with whatever else needed replacing, then test it. Of course, metal mags can get bends in the body, but polymer mags usually don't have that problem. They just crack or split on the welded seam.

I disagree had seen some people have 30rd GI mags for over 15 years used thousands of times still work fine. Think the writer is over zealous and has a BIG check book on regards to mags. My opinion just clean them and store them right they last forever.

Just to inform you that the writer does not have a big checkbook on anything of the kind. All his feedback comes from real-world experience. And I didn't think there was any zeal out of the ordinary. I feel it was very objective and informative.

If the spring can take a set then the spring is crap and was not make to the spec of the mags capacity and that brand should no longer be purchased. Springs can only set when collapsed beyond their elastic limit, which should be set below the maximum compression for the magazine capacity. Furthermore, springs only loose elasticity through cycles of compression/decompression numerous times, not from sitting under an appropriate load.

Given the past quality of USGI mags, they should be considered disposable after a couple of uses.
Durability was not one of their virtues, and if found was purely accidental.

WRT pistol mags, be aware that many pistol manufacturers outsource their magazines. Beretta and Sig are two big examples. Sig uses Mec-Gar magazines, which means that for these purposes, a Mec-Gar is a “factory” mag for a Sig. This can also give you additional options. The P226, for example, comes with 15 round mags, but Mec-Gar also makes a flush-fit 18, and an extended 20. The 18s and 20s perform flawlessly, give you extra capacity, and they’re cheaper (though they’re not marked with the Sig logo, if you care about that).
It remains good advice in general, but there are exceptions besides the 1911.

All good points Gentlemen. FWIW, I have 10 Vietnam 20 rd mags that still work, Flawlessly. Would I stake my life on them…..Nope. But they work fine on the range. Just sayin.

Great article! Never knew about the trick of hitting the baseplate for checking u're feed-lips. Thumbs up!

On the topic of magazines: When it comes to HK's AR steel mags. I would not recommend loading more than 28-rounds in a 30rounder. It will not seat properly. When we first had our HK416's issued we routinely loaded 30 rounds in our mags. Only to have them fall out during shoot-and-move drills.

As one of my senior NCO's put ut "It's better to have 28 rounds ready to go in you're weapon than 30 rounds SOMEWHERE in the AO"
