If reciprocity is given complete force, then a firearm legal to carry under the CCL of one state would be legal to carry in all states--including the mags that would be legal in your home state. If full faith & credit is given full force, someone from Texas with an LTC who is legally carrying a Glock 17 with 17rd mag would be legal to carry that same Glock 17 with 17rd mag in every other state. And that would also mean that folks could carry guns that aren't on some "list", like what California has.you seem to not notice the 17 round mag in the AZ guys gun. That will get you a felony in Ca and cost you your rights to own guns.
LTC or not that 17 round mag will kill you in Ca.
National Reciprocity is a good thing. I don't see why gun folks don't embrace that fully.
