Politically the US is very much not a monolith on this topic and many states and localities have passed laws that were later struck down as unconstitutional. This is a bill in California, which does have about the strictest laws that the federation allows them to have, and they would place even stronger restrictions on guns if they could. This is not really ironic as much as it is pushing the envelope for gun control as far as they legally can.

But also, California regulators likely see the regulatory landscape as the reason this law is needed rather than in spite of it.

Gun manufacturers are likely against these types of regulations because many of them would affect manufacturers and the tools they use too.
