Golden State Arms, also known as Pasadena Firearms, was a major military surplus importer, wholesaler, and retailer, located in the Pasadena area 1952-1966. Major to the point they did short term jobs with almost every rifle stock maker, refinisher, gun machine shop, etc in the Western United States, and often nationwide, during their existence. They were the source of work and income for many different companies, most of whom were not owned and operated by the people who owned Golden State Arms.
A fair amount of incorrect information regarding Golden State Arms and the people and companies affiliated with them in various ways, has been circulated for many years and has found it's way onto many locations on the internet. What led me to research Golden State Arms were M1 carbines. What I learned as a result of the research goes far beyond M1 carbines. This research provided me with a window of opportunity to meet and interview a number of the people affiliated with Golden State Arms, companies they did business with, and companies that were founded by individuals who got their start at Golden State Arms. The high level of interest by owners of small arms manufactured, distributed, and/or sold by Golden State Arms, led to my decision to include their history on this website.
