Best .458 SOCOM Magazine: D&H Tactical .458 SOCOM 4 Round
- High quality material
- Very durable
- Reliable feeding
Best .458 SOCOM Magazine
In Wisconsin, D&H has been manufacturing gun parts for over thirty years.
D&H’s mags are all manufactured in the U.S.A. and have been battle-tested in wars around the globe by our soldiers and allies.
This is a good company to encourage the Second Amendment to add to the active defense.
There are USGI type aluminum mags that are classically styled.
The aircraft-grade aluminum alloy was heat-treated with a black Teflon finish and anodized with a hard coat.
For full safety against corrosion, the magazine spring is constructed of 17-7PH stainless steel.
These mags come with D&H’s patented big-bore follower, which is suitable for the .458 SOCOM to ensure consistent feeding.
If you want a .458 SOCOM classically designed AR mag, this is a tough option to beat.
Since you have ample shots without any extra weight, four rounds are a great deal for shooting.
In states with stringent laws on magazine capacity, this may also be beneficial.
Verdict: Best .458 SOCOM Magazine
These are fantastic magazines manufactured right here in the U.S.A. Whether you intend to use these for shooting or in a state with stringent rules, a low-capacity mag is an ideal option.
The patented follower and the corrosion-proof stainless steel spring are the top characteristics of these mags.
In a lightweight aluminum mag, the iconic USGI styling is good too.
2nd Best .458 SOCOM Magazine: CMMG MKW-15 .458 SOCOM 10 Round
- Holds up to ten rounds
- Very good grip
- Super durable
2nd Best .458 SOCOM Magazine
In Missouri, CMMG has been in business since 2002.
They specialize in the manufacturing and components of high-quality, but inexpensive, modern sports firearms.
Their keen attention to detail in the production of this mag shines through.
What CMMG did was to take a top-quality Lancer L5 Advanced Warfighter 30-round mag in 5.56 and fit it to the .458 SOCOM and make it ideal for usage.
While it is best with the .458, with 5.56×45 ammunition, this mag would always work.
It contains an impact-resistant silicone body and reinforced steel feed lips.
To avoid wear and to maintain durability, the magazine grab is also constructed of steel.
The floorplate slides on and off, making disassembly quick and easy for you.
A fully corrosion-proof spring and a non-tilt follower can be found inside.
The magazine body has a slender appearance and an internal geometry with a steady curve for consistent and smooth feeding.
For an extra positive grip, it is strongly textured.
This mag has been entirely designed, transported, made, and assembled in the U.S.A.
Verdict: 2nd Best .458 SOCOM Magazine
For most civilian activities , particularly with the large .458 SOCOM bullets, ten rounds is a nice, solid balance between weight and firepower.
There are some of the highest quality mags actually on the shelves.
The finest quality materials, reinforced steel feed lips, and excellent durability are the best qualities.
Best Lancer .458 SOCOM Magazine: Lancer Systems – AR-15 L5awm Magazine 30-rd
- Good value for money
- Transparent design
- Very damage resistant
- 30-rounds might be a bit too much for some
Best Lancer .458 SOCOM Magazine
The 30-round capacity of this Lancer robust magazine can be appreciated by anyone searching for an extended magazine.
Importantly, since it is constructed of a molded polymer and steel combination, the construction is not only robust but designed to be lightweight.
You may quickly introduce some significant heft to your build with a 30-round magazine, but here, you will have limited additional weight.
Meanwhile, since it is heat-treated to survive the high temperatures of full-auto fire, it is equipped for harsh situations.
Long-lasting performance guarantees additional corrosion tolerance.
To facilitate strong yet smooth ammo movement, wrap-around lips are securely attached and constructed of a single piece of reinforced steel to support firm but smooth ammo movement which would not deform even when a full load of the weapon is stored.
In addition, it was tested to withstand drops with no impairment from five feet up on strong concrete.
To encourage a strong grip, the exterior is both non-reflective and made of an improved texture, but would not avoid a free drop from any mil-spec magwell.
There are loads of aftermarket pouches, considering its 30-round capacity, since it is a regular US-GI spec.
Verdict: Best Lancer .458 SOCOM Magazine
The sturdy structure of the Lancer’s mag offers the strength you need to keep your rounds safe and running properly for anyone searching for a high capacity magazine.
4th Best .458 SOCOM Magazine: Hexmag True 10 Round
- US product
- Great grip texture
- Feeding is very reliable
- None really
4th Best .458 SOCOM Magazine
Established in 2013, Hexmag, a subsidiary of Sentry, a Virginia firm, focuses on high-end mags.
This is another business that always pays attention to each and every little aspect in the magazines they make.
The body of the device is constructed of their patented advanced composite PolyHex2, which offers excellent shock resistance and durability.
The Hexmag signature “Hexture” pattern is incorporated into the mag body, which resembles a honeycomb. Two roles are provided here.
It boosts the mag’s power and durability and provides you with an incredibly supportive grip.
These magazines are sold by Hexmag with a special riser mechanism.
The risers fit below the follower in the mag and monitor the power whilst maintaining the appearance of a full-sized tactical mag.
The riser is constructed of a composite lined with extra strong fabric.
The spring is constructed of corrosion-proof, heat-treated stainless steel.
A patented color-coding scheme named “HexID” helps you to easily distinguish the ammunition is loaded into a specified mag.
Without the usage of some tools, the magazine may be disassembled.
They are available in black, gray, green, or FDE in four colors.
Verdict: 4th Best .458 SOCOM Magazine
There are fantastic mags that check all the boxes that are appropriate.
Clearly, Hexmag has a commitment to innovation.
The best attributes of these mags are the patented features that improve longevity, the construction of Hexture and the composite of PolyHex2.
5th Best .458 SOCOM Magazine: C Products Defense 458 SOCOM – 10 Round
- Steel magazine
- 10 round capacity
- A bit heavy
5th Best .458 SOCOM Magazine
In 2011, C Products Defense launched and is based in Florida.
Their series of magazines has just been called Duramag. This is a fantastic stainless steel magazine with ten bullets.
They say that the magazine is primarily built to fix the durability issues encountered with larger calibers by mid-to-high volume dropout box mags.
Without heading above the full permitted mag capacity in certain jurisdictions, the ten round capacity gives you a decent amount of firepower.
These mags would become unnecessarily bulky and awkward with many more shots.
Thanks to the large scale of the .458 SOCOM, while it is just ten rounds, these mags have a size and design comparable to 30-round 5.56 mags.
The styling is similar to that of yesteryear’s iconic military-issue USGI steel mags.
Verdict: 5th Best .458 SOCOM Magazine
Some shooters prefer to keep things old school, considering all the advantages of silicone or aluminium, and stick to steel mags.
They are certainly more shatterproof than polymer and more prone to dents than aluminum, but the larger weight is the tradeoff.
The practical ten-round power and the corrosion-proof materials are the top characteristics of these mags.
Plus, the classic, mid-20th-century USGI styling would be appreciated by many shooters.
You can’t go wrong with this one if you want a mag that’s probably going to last a lifetime.
6th Best .458 SOCOM Magazine: E-lander Magazine .458 Socom 10 Round
- Highly durable steel design
- Reliable feeding
- Good value
- A bit heavy
6th Best .458 SOCOM Magazine
For over six decades, E-lander has been manufacturing magazines in Israel for the Israeli and other armed services.
When it comes to military hardware, Israel is a nation that does not play around.
You should be confident that the utmost of feature and dependability is given by their suppliers.
Special armed services and anti-terrorist groups are evaluating many of the latest E-lander models.
A steel body covered with an innovative KTL coating features E-lander mags.
The corrosion-resistant properties of the coating have been measured to survive more than 96 hours of continuous salt spray.
An advanced, state-of-the-art follower was also developed by E-lander.
It is meant both to be anti-tilt and to be self-leveling. An upgraded, strengthened version also features the floorplate.
These mags are a little bulky since they are steel, but in the durability of their strength they make up for it.
Iron is more crack-proof and more dent-proof than aluminum than silicone.
Besides, without too much weight or protrusion, the ten-round capacity offers you a fair amount of firepower.
In certain jurisdictions, ten rounds is also the permissible maximum mag power.
Verdict: 6th Best .458 SOCOM Magazine
You won’t find better quality than E-lander if you’re not scared of purchasing magazines not made in the U.S.A. but in one of our closest allies.
In some of the hardest disputes in the country, these mags have proved themselves.
Their key attributes are their corrosion-proof steel and loyal backers.
Best 7-round .458 SOCOM Magazine: Lancer Magazine – 7 Round
- Semi transparent design
- Good grip texture
- No feeding issues
- 7 rounds could be not enough
Best 7-round .458 SOCOM Magazine
For maximum flexibility and efficiency, Tromix took 5.56 magazines from Lancer and re-machined them.
As such, you can enjoy all the great features of Lancer magazines, including rust resistant, protection from drops of up to five feet on hard surfaces such as asphalt, and a black matte finish that is reflection-free.
The mixture of polymer and steel offers modest heft, yet smooth operation and clear feature, as in any Lancer magazine.
In either case, with gloved or bare hands, an increased grip texture from ribs and stippling guarantees a consistent grip.
What Tromix has achieved is make it possible to accurately feed even the most smooth or blunt-nosed .375/.458 bullets.
This magazine can hold 30 rounds of 5.56/.223 ammunition or 11 rounds of SOCOM ammo 458/375.
Before getting carried away, though, you can remember that these magazines are not designed to accommodate full-capacity .450 Bushmaster ammunition.
The only thing we’d be careful about is not wanting to get experimental and keeping to what Tromix advises.
Although you can notice they fit rounds that are not listed, we will advise you to consider your rifle’s durability.
This versatility is impressive too, but then again, that’s why we enjoy Tromix all the time.
They not only took an already-great, durable magazine and applied to it a bunch of extra life, but they’re still asking for a surprisingly low price.
Verdict: Best 7-round .458 SOCOM Magazine
In transforming Lancer’s already great magazines to a more portable alternative, anyone searching for anything especially new will enjoy what Tromix has done.
Best .458 SOCOM Drum Magazine: AR-15 – .458 Socom – 30rd Drum
- 30 round capacity
- High quality material
- Feeding is super reliable
- Not always available
Best .458 SOCOM Drum Magazine
Often, as in the case of this 30-round capacity drum for the AR-15, the best extended magazine is simply a drum.
Although it’s a rare choice that many gun owners never really try, it’s certainly worth it for both the experience and the improved reliability if they even have access to them.
When a high round count and flawless production are a must, there is a reason why drums are used for the highest levels of law enforcement and military.
Thanks to the close yet low-pressure storage, it starts with the fact that feeding is remarkably smooth and nearly error-free.
In addition, the distinctive design of the magazine means that your firearm does not bring hard-to-control height to a magazine of this scale.
The effect is a combination of a capacity of 30 rounds and reliable shooting with improved maneuverability.
This makes drums a true work-horse for someone who needs loads of shots but keeps the freedom to remain agile and not weighted down, in addition to better performance.
Although the drum itself contributes weight, and the rounds do, too, it is definitely simpler to remain agile with a drum than with a long stick.
Opportunities to purchase a drum are very uncommon since the market is very small among most weapons owners, which is bad.
That said, because of its innovation as well as its demand from the few who are in the know, this item would definitely not last long, so we highly urge you not to wait!
Verdict: Best .458 SOCOM Drum Magazine
The usage of a drum magazine is a rare pleasure that everyone, if they can, can try at least once.
It’s a novel feature few can take advantage of, in addition to enhancements in performance and nimble operation.
Best .458 SOCOM 11-round Magazine: Lancer Magazine – 11 Round
- Nice design
- 11 rounds is a nice sweet spot
- Very compatible
Best .458 SOCOM 11-round Magazine
Once again, we’re looking at Tromix, who repurposed an amazing Lancer product.
This item starts life as a mixture of steel and polymer for durable toughness, as with all Lancer magazines, which is at once corrosion-resistant, protected from drops of up to five feet high on rough surfaces such as asphalt, and withstands extreme temperatures for lengthy periods of time, even while fully automatic.
To make you stealthy everywhere, it is offered a black matte finish to avoid reflections, whilst the surface has been reinforced with stippling and ribs to ensure you have a firm grip.
What Tromix has done here is re-machine the magazine again so that you can use either of your smooth or blunt-nosed .375 or .458 rounds, and without any errors or jams, they can feed properly.
In addition to the 11 rounds of the .458 or .375 bullets, these magazines are entirely available when fitted with 30 rounds of 5.56 or .223 ammunition.
This offers outstanding flexibility for those who have a number of constructions for various purposes who want to compete in groups where any form of ammunition may be included, as with their other member on the roster who is a repurposed Lancer.
That said, don’t get too carried away with the flexibility and stick to the guidelines of Tromix.
They suggest that it not be used at maximum capacity with .450 Bushmaster ammunition.
In addition, Tromix brand feed followers or base plates are not delivered with them.
Verdict: Best .458 SOCOM 11-round Magazine
In addition to the longevity of the base Lancer journal, Tromix repurposed this Lancer magazine, so you will have more versatility in what you plan to use it for.
10th Best .458 SOCOM Magazine: Magpul – AR-15 30rd Pmag Gen M2 Moe Magazine 223/5.56
- Very good grip surface
- 30 rd magazine
- Extremely durable
10th Best .458 SOCOM Magazine
Our top budget choice for a spare magazine is this deal from Magpul, hands-down.
This is in no small part because of the stable architecture that you can conveniently leave fully loaded without fear of performance problems.
It is self-lubricating, corrosion-proof and constructed of fiber reinforcement from one single piece of molded polymer.
It has no joints or spot welds that would negatively impact the follower owing to this design.
In addition, the layout is a slick curve for smooth motion, whereas an anti-tilt follower helps balance the stack and prevent failures of some sort of nose-diving or bolt-over-head.
It’s also designed to last. Pressure-treated and designed with a tension relief stainless-steel spring, it can completely endure sustained exposure to excessive heat.
This is a dire need to last for a long period while working with the .458 SOCOM.
The magazine is also fitted with external ribs for superior control, and instead of the usual pit, a grab notch guarantees that debris and dirt remain away.
When you retrieve the magazine from pouches or holsters, you can quickly grasp the ledge on the floorplate, and it easily extracts the magazine for easy cleaning.
Finally, for those who wish to hold themselves fully stealthy or clearly fit their rifle’s finish, it is even available in black.
Verdict: 10th Best .458 SOCOM Magazine
This unit is inexpensive and wonderfully built to guarantee constant top-notch performance, and an incredible magazine from Magpul all around.
Why are spare magazines a must?
If you’re always on the fence regarding loading up on extra mags, the following benefits you simply can’t have any other route should be taken into account:
If you find an issue with a current magazine, you would then have to fix the issue right here and there or feed a fresh magazine. You don’t have the above alternative if you don’t have a spare, simple as that.
You’ll like another magazine if you want to bring further rounds without needing to reload too much. Getting a variety means that as many rounds as the occasion calls for, you can be prepared.
Even more Shots
Simply feeding a new magazine with or without an expanded volume implies not having to contend with the inconvenience of a manual reload. The difference between catching your goal or having it get away may imply this time-consuming procedure.
If you are using a stock magazine, you should be advised that your feeding experience can dramatically enhance the improved grip you will get with additional mags.
Spare magazines are a nice idea all of the time. With the .458 SOCOM, it is important to have a durable magazine that complements your shooting needs, so use our guide to know what to search for and select from our reviews to guarantee you you only get the best.
About the 458 SOCOM calibre
Prompted by the lack of power offered by the 5.56 NATO cartridge used in the M4 carbine and the M16 rifle, the .458 SOCOM came about from informal discussion of members of the special operations command, specifically Task Force Ranger’s experience that multiple shots were required to incapacitate members of the opposing force in Mogadishu during Operation Gothic Serpent.
Many Somalis would chew the drug Khat all day and the effects of the drug would both curb their appetite (in a country plagued by famine) and increase their pain tolerance.
Marty ter Weeme of Teppo Jutsu designed the cartridge in 2000 and Tony Rumore of Tromix was contracted to build the first .458 SOCOM rifle in February 2001.
SOCOM is the acronym for the Special Operations COMmand.
The project sponsor set forth a number of specific requirements namely that the cartridge had to fit in the M4 carbine and be capable of firing heavy-for-caliber projectiles at subsonic velocity using suppressors.
During the development phase, various other cartridges were considered and proposed to the project sponsor, but rejected as not meeting all the requirements.
The cartridges considered were 7.62×39mm, 9×39mm Grom, .45 Professional (which has since become the .450 Bushmaster), and .50 Action Express.
At the time, the .499 LWR cartridge was still in development phase and had not been chambered commercially.
The .45 Professional was ruled out because, in an interview with industry press, the developer of said cartridge stated that steel proprietary to General Motors was used in the bolts and extractor to withstand the high operating pressures.
The .50 AE and .499 LWR were ruled out because in 2000 only two bullets were offered in .501 diameter, both developed as pistol bullets for the .50 AE and not heavy enough for the subsonic suppressed role.
Research had indicated that a short belted cartridge called the .458 × 1.5″ Barnes had been adopted for use in suppressed bolt-action rifles for use in SE Asia during the Vietnam War.
It was shown as effective in terms of ballistics, firing a 500 grain bullet subsonically, but not ideally suited for its role due to the size and weight of the platform.
Combined with the wide selection of bullets available in .458 diameter, this cemented the choice of caliber.
The cartridge case design was finalized based on discussions with Tony Rumore at Tromix suggesting a lengthened .50 AE case would work well in the magazines as well as be the largest diameter case to be able to feed through the barrel extension.
The initial prototype brass still bore the .50 AE head stamp and this has caused some confusion, as the SOCOM case is longer with a narrower rim.
The .50 AE rim diameter was reduced from .514 inch to .473 inch for compatibility with other platforms, primarily bolt-action rifles.
The .473-inch/12mm-diameter rim was designed in 1888 for the German Commission Rifle chambered in 7.92×57mm Mauser cartridge, and is arguably the most common rim size globally, as all bolt actions chambered in cartridges derived from that shell, such as .30-06 Springfield, .308 Winchester or cartridges derived from them share this rim size.
The case length was chosen to be compatible with the Barnes 300-grain X Spitzer bullet.
The final case design has base and rim dimensions identical to the .425 Westley Richards, although making .458 SOCOM cases from it is impractical due to the high cost of .425 brass.
In 2009, Barnes developed a new bullet specifically for use in the .458 SOCOM, the 300 grain Tipped Triple Shock X, also known as the TTSX or TAC-X.
As noted above, the cartridge was designed to be 100% compatible with the M4 platform.
This included the buffer, buffer spring, NATO magazines, many aftermarket .223/5.56 magazines, and magazine well. In .223/5.56 caliber, cartridges stack in a staggered (double stack) fashion.
However, with the much larger .458 SOCOM, rounds “single stack” without any modification to the standard GI magazine feed lips or follower.
A standard 20-round 5.56mm NATO magazine can hold seven .458 SOCOM rounds and a standard 30-round 5.56mm NATO magazine can hold ten .458 SOCOM rounds.
The 458 SOCOM is primarily designed and used in AR15/M4 rifles.
However, several companies now offer bolt action and lever action rifles chambered for the round
