Understanding Detachable Magazines: Definition And Functionality

what constitutes a detachable magazine on a gun

A magazine is an ammunition storage and feeding device for a repeating firearm, which can be integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and pushing each one into a position where it can be readily loaded into the barrel chamber. The first successful semi-automatic pistol with a detachable box magazine was the Borchardt C-93 in 1893, and nearly all subsequent semi-automatic pistol designs adopted this feature. The magazine is assembled from inexpensive stamped sheet metal and includes a crucial safety feature: when empty, the follower stops the bolt from engaging the chamber, informing the operator that the gun is empty.

The difference between a 'clip' and a 'magazine'

Although the terms "clip" and "magazine" are often used interchangeably, even in World War II movies, they are technically different. A magazine is a device that allows you to quickly load multiple rounds into firearms, particularly semi-automatic guns. It is a storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). It is assembled from inexpensive stamped sheet metal and comes in many shapes and sizes. Magazines consist of four parts: a spring, a spring follower, a body, and a base.

A clip, on the other hand, is an accessory device used to help load ammunition into a magazine or cylinder. It holds the rounds together, making it easier to insert them into the magazine for quick reloading and firing. Clips can be constructed of one continuous piece of stamped metal and contain no moving parts. They are used to load or direct ammunition into a magazine, but not the other way around.

To load rounds into a magazine without a clip, one simply presses the spring tab down with their thumb to create room for the cartridge to slide below the lips of the housing. The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action.

While magazines are inserted into the magazine well of a gun, clips are used to hold ammunition that is then inserted into a magazine. This is the fundamental difference between the two.

The history of the detachable magazine

Gun magazines have been a vital part of the firearm industry for almost 250 years, with invention attempts dating back even further. The first guns lacked magazines since all the ammunition was loaded directly into the chamber. However, repeating firearms required ammunition storage pieces, and the first mass-produced magazine was introduced in 1779. This was a fixed tubular magazine, implemented in the Girandoni air rifle, which could hold 20 balls.

The first successful semi-automatic pistol was the Borchardt C-93, introduced in 1893, which incorporated detachable box magazines. Nearly all subsequent semi-automatic pistol designs adopted detachable box magazines. The Swiss Army evaluated the Luger pistol using a detachable box magazine in 1899 and adopted it in 1900 as its standard sidearm.

The Lee-Metford rifle, developed in 1888, was one of the first rifles to use a detachable box magazine, and the spare could be worn on soldier equipment. The first completely modern removable box magazine was patented in 1908 by Arthur Savage for the Savage Model 99, although it was not implemented until 1965. James Paris Lee's patent of November 4, 1879, predated Arthur Savage's magazine and was used on the Remington Lee model 1899 factory sporting rifle.

The increased use of semi-automatic and automatic firearms led to the detachable magazine becoming increasingly common. During World War One, detachable box magazines were used in all manner of firearms, such as pistols, light-machine guns, submachine guns, semi-automatic and automatic rifles. However, after the war, military planners maintained their traditional views and preference for clip-fed bolt-action rifles.

Detachable magazines are designed to be attached and removed from the firearm and can be loaded separately. This allows the user to carry multiple pre-loaded magazines and quickly switch between them. They are generally loaded at the bottom of the firearm, but there are exceptions, such as the Sten and Sterling submachine guns, which have magazines attaching to the side of the firearm.

How to load a magazine

A magazine is an ammunition storage and feeding device for a repeating firearm, which can be integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and pushing each one into a position where it can be readily loaded into the barrel chamber by the firearm's moving action.

  • Orient the magazine in your support hand so that the angle of the follower (the top plate inside the magazine that is mounted to the top of the spring) matches the angle of your thumb.
  • Take a round in your strong hand fingers so that you can read the stamping on the back of the cartridge.
  • Brace against a table or bench, use the ammo round to press down on the follower and slide the round under the feed lips (the curved parts that look like wings) of the magazine.
  • Use your support hand thumb to press down on the rounds already in the magazine to help relieve some of the spring tension.
  • Once the magazine is loaded, insert it into the magazine well of the gun. In a pistol, the well opens at the bottom of the grip. For rifles and shotguns, the mag well is located in front of the trigger, at the bottom of the receiver. Ensure that the bullets are pointed forward when inserting the magazine.

It is important to note that magazines and clips are different. Magazines hold individual rounds in a tube and feed them automatically through spring tension, while clips hold multiple rounds together as a unit, which is then manually fed into the gun.

Magazine jams and troubleshooting

A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action.

Magazine jams can be caused by various factors, and troubleshooting can depend on the specific type of firearm and magazine involved. Here are some general steps to identify and resolve magazine jams:

  • Identify the type of jam: Jams can occur due to various reasons, such as failure to feed, failure to advance, failure to chamber, failure to fire, failure to extract, or failure to eject. Understanding the specific type of jam can help in troubleshooting.
  • Check the magazine spring: A weak magazine spring is a common cause of jams, especially if the last round in the magazine is not being fed properly. Try replacing the magazine spring with a new one or using a different weight spring. Ensure that the high end of the spring is in the front of the magazine body, as recommended by some gun enthusiasts.
  • Inspect the magazine lips: The "lips" or "feed lips" of the magazine are crucial for feeding ammunition properly. If they are misaligned, it can cause feeding problems. Use a pair of needle-nosed pliers to gently lift and realign the lips, making slight adjustments until the desired alignment is achieved.
  • Switch magazines: If the gun continues to jam, try using a different magazine to see if the problem persists. If the issue occurs only with certain magazines, it may be due to manufacturing defects or variations in tolerances.
  • Contact the manufacturer: If the problem persists or you are unsure about the cause, contact the gun or magazine manufacturer for further guidance. They may recommend specific troubleshooting steps or suggest replacing certain parts.

It is important to note that proper maintenance and care of firearms and magazines are essential for safe and reliable operation. Always follow the manufacturer's instructions and guidelines for cleaning, lubrication, and maintenance to ensure optimal performance and minimize the risk of jams.

Single-stack vs double-stack magazines

A magazine is an ammunition storage and feeding device for a repeating firearm. It can be integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes referred to as a "clip", although this is technically inaccurate as a clip lacks a feed mechanism.

Now, when it comes to single-stack vs double-stack magazines, there are several factors to consider:

Capacity

A single-stack magazine holds its rounds in one column, while a double-stack magazine holds its rounds in a zigzag arrangement, with cartridges in two staggered columns. This makes a double-stack magazine wider than a single-stack magazine. The wider design of a double-stack magazine allows it to accommodate about 1.5 times more ammunition in the same vertical space. For example, a six-round single-stack G43 magazine can be compared to a double-stack Glock G17 magazine, which holds 17 rounds.

Concealability

The width of the magazine can affect the concealability of the firearm. A single-stack magazine allows for a thinner gun grip and an overall slimmer firearm, making it easier to conceal. In contrast, a double-stack magazine, due to its greater width, can be more challenging to conceal, especially in certain types of clothing. This consideration may be important for those who need to carry a concealed firearm, such as law enforcement officers or those with a concealed carry permit.

Ease of Use

Single-stack magazines are generally easier to handle for shooters with smaller hands due to their smaller grip and thinner profile. They are also lighter in weight, making them more comfortable to carry for extended periods. On the other hand, double-stack magazines offer the advantage of increased ammunition capacity, reducing the need for frequent reloading.

Reliability

Some users report that single-stack magazines with a capacity of more than 12 rounds may experience feeding issues, while double-stack magazines tend to be more reliable as the capacity increases. This could be a factor for those who anticipate the need for rapid-fire capabilities or find themselves in situations where reliability is critical.

Legal Considerations

It is important to consider the local laws and regulations regarding magazine capacity. Some jurisdictions may have restrictions on the number of rounds allowed in a magazine. For example, in New York, 10-round magazines are legal but become illegal if loaded with more than seven rounds. Therefore, it is essential to be aware of the legal requirements in your area or any region you plan to travel to with your firearm.

In summary, the choice between a single-stack and a double-stack magazine depends on various factors, including capacity, concealability, ease of use, reliability, and legal considerations. Both types of magazines have their advantages and disadvantages, and the best option depends on the specific needs and circumstances of the user.
