👉 The Southampton Weapon, also known as the "Southampton Gun," is a unique and controversial firearm designed by John M. Thompson in 1968. It is a semi-automatic, gas-operated pistol that uses a novel design featuring a detachable, spring-loaded bolt. This innovative mechanism allows for rapid fire without the need for manual reloading, making it a formidable weapon in close-quarters combat situations. However, its unconventional design and the potential for accidental discharge have led to significant safety concerns and legal challenges. Despite its effectiveness in certain scenarios, the Southampton Weapon remains largely restricted due to these issues and is not widely recognized or legally produced outside of niche circles.
