Introduction
The M1 Thompson submachine gun, often simply referred to as the “Tommy Gun,” is an iconic firearm, a symbol of an era, and a significant piece of military and cultural history. Its unmistakable silhouette, punctuated by its drum magazine and wood furniture, has cemented its place in popular imagination. From its use in World War II to its infamous association with gangsters, the Thompson’s legacy is complex and enduring. For collectors, enthusiasts, and those fascinated by history, owning an M1 Thompson represents a piece of Americana. One way to get closer to owning this legend is through the world of M1 Thompson parts kits.
Parts kits offer a unique avenue into firearms ownership. Instead of purchasing a fully assembled, ready-to-fire weapon, a parts kit consists of the disassembled components of a firearm. This allows enthusiasts to delve into the mechanics of the weapon, potentially allowing them to experience the satisfaction of assembling their own classic firearm. This guide serves as a comprehensive introduction to the world of M1 Thompson parts kits, offering crucial information for those interested in acquiring, assembling, and understanding these fascinating relics.
Understanding the M1 Thompson
To appreciate the appeal of an M1 Thompson parts kit, it’s crucial to understand the weapon itself. The M1 Thompson family of submachine guns was developed by John T. Thompson and was introduced in the early nineteen twenties. Initially designed as a “trench broom” intended to sweep through enemy lines, the weapon evolved through various models and was adopted by the U.S. military during World War II. Its heavy construction, reliable operation, and high rate of fire quickly made it a favorite among soldiers.
The M1 Thompson operates on a simple blowback principle. This straightforward design contributes to the Thompson’s reliability and ease of maintenance. The weapon fires the .45 ACP cartridge, a powerful round capable of delivering substantial stopping power at close to intermediate ranges. The M1 Thompson typically features a box magazine, holding up to thirty rounds. There are also other models with larger capacity drum magazines. The classic wooden stock, forend, and grip give the Thompson its distinctive look. The overall weight of the weapon, due to its robust build, is considerable but contributes to recoil management during rapid firing.
Compared to other weapons of its time, The Thompson submachine gun offered a high rate of fire. It could fire up to eight hundred and fifty rounds per minute in some variants.
The M1 Thompson saw several iterations. While early models, such as the M1928A1, were complex and expensive to manufacture, later versions, like the M1 and M1A1, were simplified to streamline production for wartime needs. These changes involved modifying the firing mechanism and replacing some parts with more easily mass-produced components. These differences, while subtle, contribute to the historical significance and collector value of specific Thompson models, and are important to understand when considering an M1 Thompson parts kit.
What is an M1 Thompson Parts Kit?
An **M1 Thompson parts kit** is, in its essence, a collection of components that make up a complete M1 Thompson submachine gun, sold in a disassembled state. These kits are often sourced from demilitarized or surplus firearms. The appeal of a parts kit lies in its accessibility. Instead of purchasing a fully functional firearm, which may be restricted by local laws, parts kits offer a more regulated path to ownership, allowing enthusiasts to build their own Thompson.
It is vital to understand the legal considerations surrounding parts kits. The legal status of a parts kit varies significantly based on local, state, and federal regulations. Understanding these laws is absolutely crucial. Many jurisdictions consider a parts kit to be a collection of parts, but the legal status of the receiver – the primary serialized part of the firearm – is a critical factor. If the receiver is intact, or can be easily reassembled, the parts kit might be considered a firearm, subject to all applicable regulations, including registration and background checks.
The term “demilitarized” can mean different things legally. Some receivers will be completely destroyed. Others are considered “demilled” by means of a cut in the side, the removal of critical parts. A demilled receiver will be the most legally complex part of any parts kit build.
Be absolutely certain that you understand the relevant regulations in your area before you attempt to acquire or assemble an M1 Thompson parts kit. Ignoring these laws can have severe legal consequences. The purchase, possession, and assembly of firearms is a complex legal area.
A typical **M1 Thompson parts kit** will include most of the essential components. You can expect to find the bolt assembly, the barrel, the trigger group, and various internal and external parts. The receiver, which houses the firing mechanism and is typically serialized, is often the most critical part. It might be included in a demilled state (e.g., cut, drilled, or otherwise rendered unusable). The furniture – the stock, forend, and grip – will also be part of the kit, which often includes the magazine well. The presence and condition of each component will influence the overall value and desirability of the kit. Missing springs, pins, or small parts are common in a parts kit, making a complete inventory essential to the building process.
Sourcing M1 Thompson Parts Kits
Finding a legitimate and reliable source for an **M1 Thompson parts kit** is the first hurdle to overcome. There are several avenues that enthusiasts can explore, each with its own set of considerations. Choosing a reputable supplier is essential to ensure the authenticity, condition, and legality of the components.
Established dealers specializing in firearms and military surplus often carry **M1 Thompson parts kits**. These vendors typically have a strong reputation for quality, customer service, and compliance with relevant laws. They can offer a level of expertise and assurance that is often absent in other marketplaces. Researching vendors before making a purchase is critical. Check online reviews, ask for references, and verify that they are licensed and authorized to sell firearm components.
Online marketplaces and auction sites provide another avenue for sourcing **M1 Thompson parts kits**. Platforms like GunBroker and other firearms related websites can have a wide selection. However, purchasing from these platforms requires a heightened level of caution. The buyer must carefully inspect all the included parts. Be sure to ask the seller any questions to clear up concerns about the condition of the kit, and confirm its legal status.
Before making any purchase, consider several factors. The condition of the parts kit is a primary concern. Kits can vary greatly in terms of wear and tear. Decide how important a pristine condition is to you. Completeness is another important factor. Verify that all the essential parts are present, or if not, plan to source them. Price and value also play a role. Determine what you are willing to pay. Research average market prices.

Acquiring an M1 Thompson parts kit is the first step toward building your own classic. The next step is to assemble the firearm. The receiver, if you are not purchasing a pre-manufactured one, is usually the most challenging component to deal with.
The receiver is the heart of the firearm, housing the firing mechanism and often bearing the serial number. If the receiver in your kit is demilled, it will need to be repaired or replaced. Building or repairing a receiver often requires specialized tools, skills, and in some cases, is highly regulated. There are several options to get a receiver. Some people purchase a commercially manufactured receiver. You can also look for demilled receivers that are in good condition, as a start to a new build.
Once a receiver is acquired, you can begin assembly.
The assembly process generally involves several steps. Start by acquiring a suitable work area. You will need a variety of tools, including a vise, punches, drill press, files, and measuring instruments. Speciality tools for Thompson builds will also be needed. Some of these tools, like the Thompson barrel wrench, are specialized.
Start with the core components. This can involve fitting the bolt and the barrel into the receiver. Precise measurements and adjustments are critical for proper function and safety. You then fit the barrel to the receiver. Next the trigger group will be put in. Each part must be correctly fitted and installed to ensure safe and reliable operation. Once this assembly is complete, the various small parts, pins, and springs will be put in.
After the main components have been assembled, you can begin assembling the various internal mechanisms. After everything is installed, you can begin test firing. Always consult with a competent gunsmith before test-firing any newly constructed firearm.
Building a firearm can be dangerous. Always wear appropriate safety equipment. When test firing, use protective eye and ear protection and always follow safe gun-handling practices.

Storage is essential for preventing damage and corrosion. Store your M1 Thompson in a cool, dry place. Avoid storing it in a damp environment, which can promote rust. Consider using a gun safe or a secure cabinet to protect the weapon from unauthorized access.
Customization and Accessories
The appeal of a classic like the M1 Thompson extends beyond its performance and historical significance. Customization can allow you to personalize your weapon. Different stocks, grips, and forends can be installed. Slings can be added to ease carrying. Aftermarket sights can improve accuracy. Before making any changes to your M1 Thompson, make sure that any changes you make are fully legal in your area.
