To add to hrdware's post, you can find more detail information here, a link to the final version of the bill: http://webserver1.lsb.state.ok.us/cf...1733 ENR.DOC.

To specifically answer your question about businesses, the new legislation does not change the original language in the most recent version of the Oklahoma Self-Defense Act.

TITLE 21 § 1290.22 BUSINESS OWNER’S RIGHTS

A. Except as provided in subsection B of this section, nothing contained in any provision of the Oklahoma Self-Defense Act, Section 1290.1 et seq. of this title, shall be construed to limit, restrict or prohibit in any manner the existing rights of any person, property owner, tenant, employer, or business entity to control the possession of weapons on any property owned or controlled by the person or business entity.

B. No person, property owner, tenant, employer, or business entity shall be permitted to establish any policy or rule that has the effect of prohibiting any person, except a convicted felon, from transporting and storing firearms in a locked vehicle on any property set aside for any vehicle.
