.458 SOCOM Magazines – Honest, Tell All Review 2022

Best Overall:
D&H Tactical .458 SOCOM 4 Round

D&H has been producing firearms components for over thirty years in Wisconsin. D&H's mags are all made in the U.S.A. and have been battle tested by our troops and allies in conflicts around the world. This is a good company to support to contribute to its active defense of the Second Amendment.

These are classically-styled USGI style aluminum mags. The aircraft-grade aluminum alloy has been heat-treated and hard coat anodized with a black Teflon finish. The magazine spring is made of 17-7PH stainless steel for complete protection against corrosion. These mags come with D&H's proprietary big-bore follower, which is perfect for ensuring reliable feeding with the .458 SOCOM.

If you want a classically-styled AR mag in .458 SOCOM, this is a hard option to beat. Four rounds are a great amount for hunting because you have enough shots without any excess weight. This can also be useful in states with restrictive laws on magazine capacity.

Bottom Line

These are great magazines made right here in the U.S.A. If you intend to use these for hunting or in a state with restrictive laws these are an excellent choice for a low-capacity mag. The top features of these mags are the proprietary follower and the corrosion proof stainless steel spring. The classic USGI styling in a lightweight aluminum mag is nice too.

Runner-up:
CMMG MKW-15 .458 SOCOM 10 Round

CMMG has been in business in Missouri since 2002. They specialize in producing high-quality, yet affordable, modern sporting rifles and their components. Their careful attention to detail comes through in the design of this mag.

What CMMG has done is to take a top-quality Lancer L5 Advanced Warfighter 30-round mag in 5.56 and adapt and perfect it for use with the .458 SOCOM. Although it is ideal for the .458, this mag will still operate with 5.56x45 ammo. It features an impact-resistant polymer body and feed lips made of hardened steel. The magazine catch is also made of steel to prevent wear and ensure reliability.

The floorplate slides on and off, giving you quick and easy disassembly. Inside you will find a completely corrosion-proof spring and a non-tilt follower. The magazine body has a slim profile and a constant curve internal geometry for reliable and smooth feeding. It is heavily textured for an extra positive grip. This mag has been designed, tooled, manufactured, and assembled entirely in the U.S.A.

Bottom Line

Ten rounds is a good, solid compromise between weight and firepower for most civilian tasks, especially with the large .458 SOCOM rounds. These are some of the best quality mags on the market today. The best features are the top quality materials, the hardened steel feed lips, and superior reliability.

Best for the Money:
Magpul - AR-15 30rd Pmag Gen M2 Moe Magazine 223/5.56

Our top budget pick for a spare magazine is hands-down this offering from Magpul. This is in no small part due to the rugged design which you can comfortably leave fully loaded without fear of performance concerns. It is self-lubricating, corrosion-proof, and made of one single piece of molded polymer with fiber reinforcement. Owing to this design, it has no joints or spot welds that may adversely affect the follower.

Additionally, the design is a slick curve for smooth movement while an anti-tilt follower helps to stabilize the stack and prevent any nose-diving or bolt-over-head type of failures.

It’s designed to last, too. Heat-treated and built with a stainless-steel spring with stress relief, it can fully withstand prolonged exposure to intense heat. When dealing with the .458 SOCOM, this is a dire necessity to last a long time.

Additionally, the magazine is equipped with exterior ribs for superior grip and a catch notch instead of the typical hole ensures that debris and dirt stay away.

You’ll easily grasp the ledge on the floorplate when you extract the magazine from pouches or holsters, and it removes from the magazine easily for a quick clean.

Finally, it is available in black as well, for those who want to keep themselves completely stealthy or simply match their rifle’s finish.

Bottom Line

An incredible magazine from Magpul all around, this unit is affordable and beautifully designed to ensure consistent top-notch performance.

4. Hexmag True 10 Round

Hexmag, a subsidiary of Virginia company Sentry, was founded in 2013 and focus on high-end mags. This is another company that really pays attention to each and every little detail of the magazines that they produce.

The product’s body is made of their proprietary PolyHex2 advanced composite, which provides outstanding shock resistance and reliability. Built into the mag body is Hexmag's signature "Hexture" pattern which resembles a honeycomb. This provides two functions. It increases the strength and durability of the mag and gives you an extremely positive grip.

Hexmag offers these magazines with a unique riser system. The risers fit in the mag below the follower and regulate the capacity while retaining the look of a full-sized tactical mag. The riser is made of an extra durable fiber reinforced composite. The spring is made of heat-treated, corrosion-proof stainless steel.

A proprietary "HexID" color-coding system gives you quick identification of which ammo is loaded in a given mag. The magazine can be disassembled without the use of any tools. They are available in four colors, Black, Gray, Green, or FDE.

Bottom Line

These are great mags that tick all the right boxes. Hexmag clearly has a dedication to innovation. The best features of these mags are the proprietary features that increase durability, the Hexture design and the PolyHex2 composite.

5. C Products Defense 458 SOCOM - 10 Round

C Products Defense started out in 2011 and is based in Florida. They have recently renamed their line of magazines to Duramag. This is a great ten-round stainless steel magazine. They claim that the magazine is designed specifically to address the reliability problems that mid-to-high capacity dropout box mags face with larger calibers.

The ten round capacity gives you a good amount of firepower without going over the maximum allowed mag capacity in many states. With many more rounds, these mags would become excessively heavy and cumbersome.

Although it is only ten rounds, thanks to the large size of the .458 SOCOM, these mags have a similar size and style to 30-round 5.56 mags. The styling is close to that of the classic military-issue USGI steel mags of yesteryear.

Bottom Line

Despite all the benefits of polymer or aluminum, some shooters like to keep it old school and stick to steel mags. They are definitely more shatterproof than polymer and more dent-resistant than aluminum, but the tradeoff is the greater weight.

The top features of these mags are the practical ten-round capacity and the corrosion-proof materials. Plus, many shooters will appreciate the classic, mid-20th-century USGI styling. If you want a mag that will definitely last a lifetime, you can't go wrong with this one.

6. E-lander Magazine .458 Socom 10 Round

E-lander has been producing magazines in Israel for the Israeli and other militaries for over six decades. Israel is a country that does not mess around when it comes to military hardware. You can be sure that their suppliers provide the ultimate in function and dependability. All of E-lander's new designs are tested by special military forces and anti-terrorist units.

E-lander mags feature a steel body coated in an advanced KTL coating. The coating's corrosion-resistant properties have been tested to stand up to over 96 hours of constant salt spray.

E-lander has also designed an advanced, state-of-the-art follower. It is designed to be both anti-tilt and self-leveling. The floorplate also features an improved, reinforced design. As they are steel, these mags are a bit heavy but make up for it in the durability of their construction. Steel is more crack-proof than polymer and more dent-proof than aluminum.

Besides, the ten-round capacity gives you a reasonable amount of firepower without too much weight or protrusion. Ten rounds is also a legal maximum mag capacity in many jurisdictions.

Bottom Line

If you're not shy of buying magazines not made in the U.S.A. but in one of our closest allies, you won't find better quality than E-lander. These mags have proven themselves in some of the toughest conflicts in the world. Their top features are their corrosion-proof steel and reliable follower.

Best .458 Socom 7-Round Magazine: 
Lancer Magazine – 7 Round

Tromix has taken Lancer 5.56 magazines and re-machined them for optimum versatility and performance. As such, you’ll enjoy all the great features of Lancer magazines, which include corrosion resistance, protection from drops of up to five feet onto hard surfaces like concrete, and a reflection-free black matte finish.

As with any Lancer magazine, the combination of polymer and steel provides minimal heft but smooth operation and consistent function. An improved grip texture from ribs and stippling ensures a constant hold in any conditions, with gloved or bare hands.

What Tromix has done is allow for even your most flat or blunt-nosed .375/.458 bullets to properly feed. This magazine is capable of handling 30 rounds of 5.56/.223 ammunition or 11 rounds of 458/375 SOCOM ammo. You should note before getting carried away, however, that these magazines are not built for handling .450 Bushmaster ammo with full capacity.

The only thing that we would caution is to not try to get experimental and stick to what Tromix recommends. While you may find that they accommodate rounds that are not specified, we would encourage you to respect the longevity of your rifle.

This versatility is truly remarkable, but then again, that’s why we always love Tromix. Not only have they taken an already-great, durable magazine and added a lot of extra life to it, but they’re asking a shockingly low price, too.

Bottom Line

Those looking for something particularly unique will love what Tromix has done in adapting Lancer’s already great magazines to a more versatile option.

Best .458 Socom Drum Magazine:
AR-15 - .458 Socom Drum

Sometimes, the best extended magazine is actually a drum, as in the case of this 30-round capacity drum for the AR-15. While it’s a unique option that many gun owners actually never try out, if they even have access to them, it’s definitely worth it for both the experience and the enhanced reliability.

There is a reason that drums are used by the highest levels of law enforcement and military when a high round count and perfect performance are a must. It begins with the fact that feeding is exceptionally smooth and virtually error-free thanks to the tight but low-pressure storage. Additionally, the unique shape of the magazine ensures that a magazine of this size does not add difficult-to-control height to your weapon.

The result is a combination of a 30-round capacity and consistent shooting with increased maneuverability. This, on top of the improved performance, makes drums a real work-horse for anyone who wants lots of shots but retain the ability to stay mobile and not weighed down.

While the drum itself does add weight—and necessarily, the rounds do, too—it is certainly easier to stay nimble with a drum than a long stick.

Opportunities to use a drum are exceedingly rare as the demand among most gun owners is quite low, which is unfortunate. That said, this item will probably not last long due to its novelty as well as its demand from the few who are in the know, so we strongly urge you to not delay!

Bottom Line

Using a drum magazine is a unique experience that everyone should try at least once, if they can. In addition to improvements in performance and nimble operation, it’s a novel feature few will take advantage of.

Best .458 Socom 11-Round Magazine: 
Lancer Magazine – 11 Round

Once again, we look to Tromix, who has repurposed an excellent Lancer product. As with all Lancer magazines, this item starts life as a combination of steel and polymer for rugged durability that is at once corrosion-resistant, safe from drops of up to five feet high onto hard surfaces like concrete, and withstands intense temperatures for long durations of time, even when on full-auto.

It is given a black matte finish for resistance to reflections to keep you stealthy anywhere, while the surface has been enhanced with stippling and ribs to ensure you have a solid grip.

What Tromix has done here is once again re-machine the magazine so that you can use any of your flat or blunt-nosed .375 or .458 rounds, and they will feed properly without any errors or jams.

These magazines are fully functional when equipped with 30 rounds of 5.56 or .223 ammunition in addition to 11 rounds of your .458 or .375 ammunition. As with their other entrant on the list which is a repurposed Lancer, this provides excellent versatility for those who have a variety of builds for different occasions or want to hunt in groups where either ammo type can be used.

That said, don’t get too carried away by the versatility and stick to Tromix’s guidelines. They recommend it not be used with .450 Bushmaster ammo at full capacity. Additionally, they do not ship with Tromix brand feed followers or base plates.

Bottom Line

Tromix repurposed this Lancer magazine, meaning you can have great versatility in what you choose to use it for, in addition to the durability of the base Lancer mag.

Best Lancer .458 Socom Magazine:
Lancer Systems - AR-15 L5awm Magazine 30-rd

Those looking for an extended magazine will enjoy the 30-round capacity of this rugged magazine from Lancer. Importantly, the design is not only durable but designed to be lightweight, as it is made from a combination of molded polymer and steel. A 30-round magazine can easily add some serious heft to your build, but here, you’ll have minimal additional weight.

Meanwhile, it’s ready for extreme conditions, as it is heat-treated to withstand the high temperatures of full-auto fire. Additional corrosion resistance ensures long-lasting performance.

Wrap-around lips are permanently attached and made from a single piece of hardened steel to promote firm but smooth ammo movement and won’t deform even when the magazine is kept stored with a full load. Additionally, it has been tested to survive drops from five feet high onto solid concrete with no impairments.

The exterior is both non-reflective and composed of an enhanced texture to promote a solid grip, but won’t impede a free drop from any mil-spec magwell.

Despite its 30-round capacity, there are plenty of aftermarket pouches, as it is a standard US-GI spec.

Bottom Line

For those looking for a large capacity magazine, the rugged construction of Lancer’s mag provides the strength you need to keep your rounds safe and functioning properly.
