The bill amends Section 1290.6 of the Oklahoma Self-Defense Act by removing the prohibition on certain types of ammunition, specifically deleting the restriction on ammunition that is larger than .45 caliber. This change allows individuals carrying a concealed or unconcealed handgun, in accordance with the provisions of the Oklahoma Self-Defense Act, to use a broader range of ammunition without it being classified as a prohibited weapon.

Additionally, the bill maintains the penalties for violations of this section, which include criminal prosecution and an administrative fine of $500, determined by the Oklahoma State Bureau of Investigation. The effective date for this amendment is set for November 1, 2026.
