- Ammunition registration was repealed by Congress as part of the Firearms Owners Protection Act of 1986.
- SB 53 imposes identical restrictions on “handgun” ammunition to those contained in AB962. Signed into law in 2009, AB 962 has yet to be enforced due to the pending lawsuit Parker v. California in the California Supreme Court.
- In 2011, Governor Brown vetoed similar legislation sponsored by Senator de Leon. Governor Brown instructed that another ammunition registration bill should not be considered prior to the resolution of Parker v. California.
