This assembly modifies a specific model of handgun, the SD40VE, enabling it to fire continuously as long as the trigger is depressed and ammunition is available. Typically, the original firearm is designed for semi-automatic operation, requiring a separate trigger pull for each shot fired. The altered configuration bypasses this semi-automatic function, allowing for rapid, sustained firing.
The existence and distribution of such modifications raise significant legal and ethical concerns. Unauthorized alteration of a firearm to function as a machine gun is strictly regulated under federal law in the United States, as well as in many other countries. These regulations are in place due to the increased potential for misuse and the public safety risks associated with uncontrolled automatic gunfire. Historically, restrictions on automatic weapons have been implemented to reduce crime and limit the potential for civilian use in violent conflicts.
