Components of a Thompson SMG Parts Kit

A Thompson SMG parts kit is a carefully curated collection of essential components required to assemble or restore a Thompson submachine gun. Whether you’re looking to complete a project or add a significant historical piece to your collection, a typical parts kit includes the following components:

  1. Receiver: At the heart of the Thompson SMG, the receiver houses the bolt, firing mechanism, and other critical components that ensure the firearm functions appropriately.Tags:, 
  2. Barrel: Chambered in .45 ACP, the barrel of the Thompson is known for its accuracy, durability, and ability to withstand high rates of fire.
  3. Bolt Assembly: The bolt assembly includes the bolt, firing pin, and extractor. These parts are integral to the firearm’s operation, ensuring the smooth cycling of rounds.
  4. Trigger Group: Comprising the trigger, sear, and springs, the trigger group enables the firing mechanism of the firearm to function smoothly.
  5. Stock and Grip: The stock (wooden or polymer) and grip offer the shooter stability and control. The ergonomics of the Thompson SMG have made it an iconic firearm in historical and modern contexts.
  6. Magazine: Thompson SMGs typically use either stick or drum magazines, with capacities ranging from 20 to 50 rounds, allowing for sustained rapid fire.
  7. Blish Lock: A standout feature of the Thompson SMG, the Blish Lock is a unique mechanism that revolutionized the submachine gun design and contributed to its legendary status.

The Blish Lock: A Unique Mechanism of the Thompson SMG

The Blish Lock is one of the most innovative aspects of the Thompson SMG, developed by John Bell Blish. It operates on the principle that certain metals can adhere to each other under high pressure, a phenomenon known as the Blish Principle. The mechanism consists of a bronze block fitted into cuts in the receiver and the bolt. Here’s how it works and why it’s significant:

How the Blish Lock Works:

  • Upon firing, the expanding gases from the cartridge push the bolt backward.
  • The Blish Lock mechanism briefly locks the bolt in place due to the pressure created by the expanding gases, delaying the blowback action.
  • This delayed blowback allows for better control of the gases, reducing the wear and tear on the firearm and improving overall accuracy.

Advantages of the Blish Lock:

  • Reduced Wear and Tear: The Blish Lock reduces stress on the firearm’s components by delaying the blowback action.
  • Enhanced Accuracy: The mechanism helps control the release of gases, making the Thompson more stable and accurate during rapid fire.Tags:, 
  • Greater Handling of the .45 ACP Cartridge: The Thompson SMG was explicitly designed to handle the decisive .45 ACP round, and the Blish Lock improved its ability to do so more effectively.

Historical Significance:

Although the Blish Lock was eventually phased out in later models of the Thompson SMG, its inclusion in the original designs made a lasting impact on submachine gun engineering. Collectors highly value the parts kits containing the Blish Lock, representing the innovative spirit of early firearm development.
