Snap gun

A snap gun, also known as a "pick gun" or "picklock gun," is a specialized tool used for picking pin tumbler locks. It rapidly strikes all the pins in the lock simultaneously, momentarily separating the shear line, allowing the lock cylinder to be turned. Unlike traditional lock picks, which manipulate each pin individually, a snap gun uses a single, rapid action to attempt to bypass the lock's security mechanism.

The effectiveness of a snap gun varies depending on the quality and design of the lock. High-security locks often have features specifically designed to resist snap gun attacks. Furthermore, using a snap gun may leave visible marks or damage to the lock, potentially indicating unauthorized entry.

The legality of possessing and using a snap gun varies by jurisdiction. In some areas, it is considered a burglary tool and is illegal to possess without proper authorization.
