An 18-year-old from Stratford is facing charges after officers found him with one of the 111 guns stolen from the Smith & Wesson plant in 2012.
Christian King was arrested on weapons charges March 12 while officers confronted him as part of a drug dealing investigation, police said.
Officers found King in possession of a stolen .38-caliber handgun that was taken from Smith & Wesson in Springfield in Nov. 2012, according to police.
A Stratford truck driver was charged with stealing the guns and two other men were arrested for reportedly selling them in Bridgeport.
Police said 42 of the stolen guns have been recovered so far.
King was charged with the theft of a firearm, carrying a pistol without a permit and fifth-degree larceny by possession.
He was also charged on an outstanding re-arrest warrant for failing to pay a ticket.
King was held on a $300,000 bond.
