Born from the ashes of a global conflict and a post-war world of rampant change, the Thompson submachine gun, or “Tommy Gun” as it became affectionately (or fearfully) known, emerged in the early decades of the twentieth century. It wasn’t designed to be merely a firearm; it was intended to be the pinnacle of personal defense, a weapon that could dominate close-quarters combat.
The mastermind behind this innovative weapon was John T. Thompson, a man with a vision to revolutionize infantry tactics. The Thompson’s early development coincided with the end of World War I, and it found its niche in the interwar period, finding limited success in military applications but becoming a sought-after tool for law enforcement, and sadly, also for organized crime.
Its iconic features defined its identity: a compact size, chambered for pistol-caliber rounds, and capable of fully automatic fire. These characteristics, combined with its perceived stopping power, rapidly secured its fame. Different models and variants emerged, tweaking features and refining the design, but the core philosophy—a readily available stream of lead—remained consistent. The Thompson wasn’t just a gun; it was a statement.
The weapon’s impact on popular culture has been profound. From its appearance in countless films and television shows to its enduring presence in video games, the Thompson has transcended its historical origins and established a lasting presence in the collective consciousness. It is inextricably linked to the era of Prohibition, the brutal world of gangsters, and the courageous law enforcement officers who sought to bring them to justice. It became an emblem of a turbulent time, and its legacy continues to fascinate and intrigue.
The Drum Magazine: A Thompson Staple
While the Thompson could feed from box magazines, it was the drum magazine that really cemented its reputation. The 100 round drum, in particular, represented an undeniable advantage in terms of firepower.
The design itself is a marvel of engineering, a complex arrangement of components meticulously crafted to store and reliably feed a large number of cartridges. The drum magazine, typically constructed from stamped steel, boasts a robust exterior that can withstand the rigors of combat. Internal components, including a central winding mechanism and a follower that guides the cartridges, work in concert to provide a continuous supply of ammunition.
Different manufacturers have produced variations of the drum, but the underlying principle remains the same: a capacity that far surpasses the standard box magazines. The construction methods have evolved over time, reflecting advancements in manufacturing technology.
The drum magazine is more than just a container for bullets; it’s an integral component of the Thompson’s identity, and it visually and functionally defines the weapon’s place in history.
Loading and Operating the Drum Magazine
The process of loading the 100 round drum for the Thompson requires a certain level of precision. There is a winding mechanism on the drum itself that needs to be engaged to provide spring tension to feed the rounds.
To load a 100 round drum, the magazine is typically wound by hand, a process that provides the spring pressure necessary to advance the cartridges. You will need to push the cartridges into the drum, feeding them one by one, or utilizing a loader to speed up the process. During the loading process, maintaining the correct alignment of the cartridges is crucial for smooth and reliable feeding. A simple misstep can create issues down the line.
Once the drum is loaded, it must be inserted into the Thompson. The drum fits into the receiver, where the box magazine would typically go. Then, with the drum firmly seated, the operator can chamber a round and begin firing.
Operating the Thompson with a drum requires a different set of skills. The weight and balance are altered, particularly when the magazine is fully loaded, which will naturally affect how the weapon handles. It’s also important to be aware of the drum’s capacity. Having a hundred rounds at your disposal allows for extensive firing, but it also brings the need for disciplined trigger control.
When operating a Thompson, especially with the 100 round drum magazine, awareness is key. Issues like jams or misfeeds can occur, and troubleshooting them requires a good understanding of the magazine’s mechanics. While drums offer high capacity, careful examination of the ammunition and a disciplined approach to loading and maintenance are essential for reliable performance.
The Advantages and Disadvantages of the 100 Round Drum
The 100 round drum for the Thompson is a product of tradeoffs. There are significant advantages, but there are drawbacks, too.
Increased Capacity: The most obvious benefit is the sheer number of rounds available. The ability to fire a sustained stream of bullets provides a considerable tactical advantage. This extended capacity lets users engage targets for longer durations without the interruption of reloading, an undeniable advantage in the heat of the moment.
Sustained Fire: The high-capacity drum excels in situations demanding prolonged fire. The operator can lay down a significant volume of fire, suppressing enemy movement or providing covering fire. This is especially valuable in close-quarters situations.
Psychological Impact: The imposing appearance of the 100 round drum magazine inspires awe and fear. A fully loaded Thompson, especially with the 100 round drum, projects an image of undeniable power. This can demoralize opponents and give the user a psychological edge, making them hesitant to engage.
Unfortunately, there are disadvantages.
Size and Weight: Fully loaded, a 100 round drum adds considerable bulk and weight to the Thompson. This can affect maneuverability and fatigue the user, which matters in situations where speed and agility are crucial.
Reliability: Compared to standard box magazines, drum magazines can be prone to malfunctions, such as jams and misfeeds. The complex internal mechanism can be more susceptible to wear, dirt, and other conditions that affect operation.
Loading Difficulty: Loading a 100 round drum is more time-consuming and requires greater care than loading a box magazine. This can be an inconvenience during periods of stress, and it can potentially negate the advantage of increased capacity.
Cost: High-capacity drum magazines are typically more expensive than standard box magazines.
Legal Landscape and Considerations for Owners
The legal landscape surrounding high-capacity magazines varies widely depending on the jurisdiction. Federal, state, and local laws all play a role in determining whether an individual can legally own a 100 round drum magazine for their Thompson.
Federal Law: Understanding relevant federal regulations is crucial. The National Firearms Act (NFA) and other federal legislation could impact the legality of high-capacity magazines, even though the Thompson is not a machine gun.
State and Local Laws: It’s vital to research and understand state and local laws that apply to the ownership of high-capacity magazines. Some jurisdictions have imposed restrictions on the types of magazines that can be owned.

The process should include disassembling the drum as much as possible, and thoroughly cleaning all its components, including the follower, winding mechanism, and feed lips.
Lubrication: Lubrication reduces friction and prevents wear. Use a high-quality lubricant appropriate for firearms to keep moving parts functioning smoothly. Apply the lubricant sparingly, being careful not to overdo it, which could attract debris.
Storage: Store the drum magazine in a dry environment away from extreme temperatures. The magazine should be stored unloaded to help preserve the spring tension. Proper storage minimizes the risk of damage and ensures that the magazine will remain ready to function.
Alternatives and Comparisons
While the 100 round drum is a powerful addition to a Thompson, it’s not the only option.
Box Magazines: Box magazines are the standard magazine for the Thompson. Their advantages include simplicity, reliability, and ease of loading. They’re generally less prone to malfunctions than drum magazines. However, they offer a smaller capacity, meaning more frequent reloads.
