The bill amends Section 1290.6 of the Oklahoma Self-Defense Act, specifically addressing the definition of prohibited ammunition for handguns. It clarifies that any handgun, when carried in accordance with the Act, is considered a prohibited weapon if loaded with ammunition that is a restricted bullet as defined by Section 1289.19, or otherwise prohibited by law. Notably, the bill removes the previous stipulations that defined prohibited ammunition as either being larger than .45 caliber or as a restricted bullet.

Additionally, the bill eliminates the administrative penalty that previously accompanied violations of this section, which included a 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 or other applicable laws. The effective date for this legislation is set for November 1, 2025.
