The Lock Pick snap gun was originally designed for law enforcement agencies, but its use is so much more widespread today; property managers, Realtors, and even professional locksmiths know that it’s an invaluable tool to carry along when you need to get into a locked location.
A lock pick gun, also known as a snap gun, is a convenient tool to quickly open a pin tumbler-based lock. Unlike traditional lock picks that need a trial and error technique, snap guns use the law of physics, rapidly striking all the bottom pins at the same time and withdrawing in a snap.
Kinetic energy in the bottom pins transfer to the upper pins and stop completely. This turns the plug, allowing the locksmith to open the knob.
