In the 1930s, custom gas guns by FedLabs were adopted by the New York Prison department, following a sales pitch made before the APA by the president of FedLabs in Baltimore in 1931. Also in the 1930s, Federal Laboratories actively worked to sell gas guns for the purpose of strikebreaking, with one FedLabs representative firing a tear gas grenade during the 1934 West Coast waterfront strike, resulting in the death of a striker due to skull fracture. Auerbach notes, however, that despite FedLabs stated opposition to "communist" strikers, the firm continued to sell tear gas to the Soviet Union even during 1933.
