The bill amends Section 1290.6 of the Oklahoma Self-Defense Act, which pertains to prohibited ammunition for handguns. The amendments clarify that any handgun carried in accordance with the Oklahoma Self-Defense Act is considered a prohibited weapon if it is loaded with ammunition that is classified as a restricted bullet or otherwise prohibited by law. Notably, the bill removes the previous stipulation that restricted bullets must be either larger than .45 caliber or fall under specific definitions, thereby simplifying the criteria for what constitutes prohibited ammunition.

Additionally, the bill eliminates the administrative penalty that previously accompanied violations of this section, which included a potential fine of $500 determined by the Oklahoma State Bureau of Investigation. Instead, individuals found in violation will only face criminal prosecution as outlined in Section 1272 of the title. The act is set to take effect on November 1, 2026.
