I am still trying to understand the tangle of regulations and laws on pistol carrying. The DFG, DOJ, and the CA Attorney General have overall jurisdiction, but so doeas every schoold district, municipality, common carrier, county, etcetera. It is enough so at least for now I am discouraged from a pistol as a second member of the arsenal.
On the subject of legalities....

But, if it could be removed with anything less then a hacksaw and and attached to a conventional firearm it's illegal. Interpertation is subject to the local LEOs, so YMMV.
