The snap gun was developed decades ago to allow police officers who were not skilled in the art of lock picking to open locks with minimal instruction. SouthOrd has made the first real advance in snap gun technology since its invention. The new Stainless Steel LAT-17 utilizes an adjusting screw to allow the user to control the play in the trigger, and the slip resistant grips provide added comfort. Comes with picking needles, tension tool and instructions. Warranted for one year, from date of purchase, against manufacturing defects.
