AMT Lightning pistol

The AMT Lightning pistol was a .22LR-caliber semi-automatic handgun manufactured by Arcadia Machine & Tool (AMT) of Covina, California during the 1980s and early 90s.

The pistol was an unlicensed low-cost clone of the Ruger Mark II pistol and, along with the AMT Lightning 25/22 rifle, prompted a successful trademark infringement lawsuit from Ruger that helped bankrupt the company.
