The lock came into existence after Tompkins PLC, the British company that owned Smith, sold it to an Arizona company called Saf-T-Hammer in May of 2001. Tompkins had made a deal with Slick Willie, and it was so anti-gun that Smith about went belly-up. Tompkins had paid 112 million for it, and sold it for 15. The new owners threw the Clinton agreement out the window. BUT, they put on the lock.
