Non detachable magazines
How is "detachable magazine" defined?
Detachable magazine is defined in the California Code of Regulations as "any ammunition feeding device that can be removed readily from the firearm with neither disassembly of the firearm action nor use of a tool being required. A bullet or ammunition cartridge is considered a tool." The California Department of Justice originally interpreted the term "detachable magazine" as not requiring permanence beyond the use of a tool being required. The first official documentation of that position was in January of 2002 in a letter and opinion to DSA arms regarding a modification to a FAL that only used a screw to make the magazine non-detachable. That opinion was reaffirmed in the sworn testimony of Ignatuis Chinn in Hunt v. Lockyer. In 2006, DOJ attempted a rulemaking that subsequently was withdrawn to add the concept of permanence to "detachable magazine." A memo that was left posted after the rulemaking was not completed on DOJ's website was challenged as an underground regulation and DOJ agreed not to attempt to use the proposed permanence rule as rule of general applicability.
