the clinton brady bill did not make high capacity magazines vanish by magic. the glock 33 mags banned by clinton remained in circulation despite the law, and were used by criminals, law abiding gun owners, and persons with special permits.
the sunsetting of the brady bill had no effectt in california as my legislature never misses a chance to get on my nerves, yet i still have a great many magazines which exceed the 10 round capacity maximum, and i am violating no laws by retaining those magazines.
