As the title states, what's the penalty for "possession" of a 33 round magazine. For those who don't know, they only allow us 10 measly rounds here in California. What about actually "using" it (in a real-life warranted situation of course)? ... Loser enters my home, I positively identify he's an intruder, he has a gun himself and reaches for it when he sees me... I unload on his ass with my 33-rounder. Of course, there'd be numerous variables involved. But basically, if I used my gun in a lawful manner but used an "illegal" sized clip. What kind of trouble would I be in? Would the penalty be the same between the 15 and 33 round clips?
