California Assembly Bill No. 1135
(1) Existing law generally prohibits the possession or transfer of assault weapons, except for the sale, purchase, importation, or possession of assault weapons by specified individuals, including law enforcement officers. Under existing law, “assault weapon” means, among other things, a semiautomatic centerfire rifle or a semiautomatic pistol that has the capacity to accept a detachable magazine and has any one of several specified attributes, including, for rifles, a thumbhole stock, and for pistols, a 2nd handgrip.
This bill would revise this definition of “assault weapon” to mean a semiautomatic centerfire rifle or a semiautomatic pistol that does not have a fixed magazine but has any one of those specified attributes. The bill would also define “fixed magazine” to mean an ammunition feeding device contained in, or permanently attached to, a firearm in such a manner that the device cannot be removed without disassembly of the firearm action.
