A rotary activated gun locking mechanism is provided for is a revolver type handgun with an integral pick-proof lock. The lock functions by restraining the bullet chamber cylinder. A cylindrical type lock, similar to that used on vending machines, is located on the rear of the gun, right above the trigger. The lock, when engaged, allows for a pin to be extended into the bullet chamber cylinder or special lock receiving cavity where it extends into a matching hole. With the cylinder thus immobilized, it is impossible for the gun to fire as there are no bullets in the line with the firing pin. When an authorized user inserts the key into the lock, the pin can quickly be retraced to allow the gun to operate.
