Hello, hows everyone's day going? 
I have been watching the rimfire carbines like the Sig and GSG come on the market now for a couple years. I didn't pay any attention to them because the first thought through my head was, "No way in hell those are CA legal". I recently found out that they are indeed legal. My question is what is the legality of the hi-cap magazines? does the fact that it is a rimfire negate the 10 round limit? I saw a gun smith at my local gun shop walking through the store with a titanium GSG MP5sd that had a 22 round clip in it. Was this for a LEO or something or is it legal?
