In 2006 the name was reused as Iver Johnson Arms Incorporated in Florida as manufacturer and importer of firearms (from Philippines, Turkey and Belgium), including 1911-style semi-automatic pistols, but not related to the old Iver Johnson lines. As family ownership waned and outside investment via publicly traded stock and mergers/acquisitions/partnerships took hold, the company changed ownership and moved several times during its operation. They also saw the growth of the firearms business and the eventual restructuring of the company to focus on firearms and related business as they divested non-firearms concerns, such as the motorcycle business, in the face of growing firearms demand, World War I's armaments industry expansion, and other factors.

They shepherded the company through a phase of expansion, as bicycle operations grew, then converted to motorcycle manufacturing and sales. Frederick Iver, (born ), John Lovell (born ), and Walter Olof (born August 1878), each had vastly different levels of involvement in the company ranging from executive leadership to barely any involvement at all. Iver Johnson died of tuberculosis in 1895, and his sons took over the business.
