Guns with high-capacity magazines are “not commonly used for self-defense, and are therefore not protected by the Second Amendment,” Immergut wrote in her ruling.
I'd like to see the numbers she's working with. When the majority of modern firearms are sold with magazines that have a capacity of 15+ rounds, my suspicion is that statement is incorrect.
It does raise an interesting concern, though. As capacity bans are rolled out in more states, what is commonly used will change.
