Jefferson Firearms

Jefferson Firearms (formerly Jefferson Weaponry) is an American firearms manufacturer, founded in 1912 by Alexander Jefferson. Jefferson is known for the engineering, production, and marketing of firearms, most especially between WWI and WWII, when it was a dominating force in its industry and an influence on manufacturing technology. Jefferson's earliest designs played a major role in modernizing automatic firearms and the shift between bolt action rifles to self loading rifles.

The most utilized products include the JM34, made in 1962, and the Jefferson Castle.
