All I can say is, I’m glad I live in Pennsylvania. California isn’t the only state to institute approved handgun lists.  Also playing this game are Massachusetts and Maryland. Bitter has a Massachusetts compliant SIG, which basically involves drilling a hole in the chamber so you can see brass in it.  Stupid feature for stupid people, and it adds about 200 bucks to the cost of the gun.
But those features only work for people who would know enough to check the standard way, by actually checking the chamber.  It’s just a way to make selling firearms in the state more of a hassle, so fewer do, this driving up the price. Higher prices mean fewer legal gun owners, which make more onerous restrictions politically easier.
Don’t believe me? California has banned lead bullets for hunting. This is serious folks. The slippery slope is real.
