Buying Guide

Affordability

Since 458 mags are not as common as other magazines, they are generally more expensive. The first magazine in our list above is the most pricey. Buying C Products magazines is a reasonable option for those with budget constraints. While using aftermarket magazines is a practical and cheaper option, they aren’t on par with the best features and reliability of 458 mags.

458 SOCOM Magazines Capacity

The three magazines have a round capacity of 10. The #1 and #2 magazines can also hold 5.56 NATO ammo. In terms of round capacity, the former can hold more 5.56 rounds than the latter. D&H company has 4-round magazines which are rather plenty for suppressing a single assailant. Some rifle users modified their 458 mags to improve the magazine’s round seating capacity with other brands.

Grip Texture

One significant thing to consider in buying a magazine is grip texture.

The first mag we reviewed has external surfaces- ribs and stippling, which ensure grip stability and non-slippage.

As such, it is a good mag to use with your guns, especially during rainy seasons.

Construction

Polymer magazines such as those created by Lancer and Magpul are as durable as metals.
The first mag on our review has the lightest weight among the three due to its polymer body construction and steel springs. It is the best mag for wild animal hunting, or sporting ranges as its weight is less likely to limit your mobility. Furthermore, a polymer mag is more impact-resistant than an aluminum mag.

Purpose

458 mags are created to address problems related to feeding and compatibility with non-SOCOM rifles. Additionally, they are designed to upgrade the styling of classic military-issued magazines and to maximize round capacity as well as shooting experience without violating the “anti-high capacity mags” restriction in several states and jurisdictions.

458 SOCOM Magazine Durability

There’s a variety of options in the market for a mag. Still, the top three mags we outlined here have the most functional materials and best levels of durability and resistance to corrosive agents.

The magazine body of the first mag is solid and can withstand any beating that would generally destroy aluminum mags. It also has the highest level of durability despite having the lowest weight due to its components and styling.

Spring and Follower

Any gun owner should evaluate the quality of their mag followers and springs. A 458 SOCOM magazine follower has an anti-tilt design, and the springs are made of steel, which can facilitate proper feeding of the rounds from the magazine into the weapon. These features prevent wearing down of mags after extended use.

FAQs:

What’s a 458 Socom Magazine Good For?

A 458 SOCOM magazine is a good option for the storage of much larger 458-diameter rounds that can produce supersonic speed and dramatic force. It was invented for hard-hitting short-range and low-velocity rounds, which is efficient in annihilating enemy combatants, varmint hunting, self-defense, and home protection. In addition, it is compatible with many military exercises.

Will the 458 Socom Magazine Fit on a 223 Lower?

Yes. The 458 SOCOM magazine fits on a 223 lower. In terms of round magazine capacity, 30 rounds of 223 can fit into the 458 SOCOM mags. Bear in mind that it’s always best to use the 458 SOCOM rounds instead of the 223 to achieve optimum performance of your guns.

How Many 458 Socom Magazines Do You Need?

The number of 458 magazines that you need depends on your budget and your city’s existing gun laws. It’s a good idea to stock up on as many products as you want. Magazines can become worn-out, damaged, or lost, so it is best to have many reserves. If you want to go on a hunting spree, might as well add in the shopping list a 458 SOCOM drum magazine.

Is a 458 Socom Magazine Easy to Assemble and Disassemble?

Yes. A 458 magazine is easy to assemble and disassemble. It is an item touted as highly adjustable due to its resilient design and surface structure. This magazine is straightforward to disassemble as the floorplate will smoothly slide on and off. Although the magazine body is rather solid and compact, with the use of proper tools and careful hand maneuvering, disassembly and reassembly shouldn’t be cumbersome.

Our choice for the best 458 SOCOM Mag is…

Based on our reviews, CMMG MKW-15 458 SOCOM Magazine is the best mag for your AR-15 and bushmaster rifles. Compatibility with other kinds of ammunition is often the primary problem raised against this product. However, modifications in the way the feed lips hold non-458 SOCOM ammo can address this issue.

This mag can function reasonably well with ammunition other than the 458 SOCOM. Overall, it outperforms the other two models in terms of adjustability, durability, and reliability. Its price is steep, but you will get your money’s worth.
