I mean if red flag laws about assault, battery, and domestic violence charges were consistent across the board, I think we’d be in a broadly good starting point. The important thing is working backwards on issues that lead to gun violence in the first place, not just the ease of access.
Prohibiting especially violent people, like actual domestic and sexual abusers, murderers, etc from owning firearms is fine in my mind. The other ways that blue states have been instituting red flag laws, like expanding DV charges to include two friends consensually wrestling, denial of due process, and usurpation of firearms rights without evidence or conviction are what the 2A Absolutists take issue with.
Not to mention that if our legislature actually wanted to make the firearms laws prohibit especially dangerous people from owning, using, possessing firearms, they could just fix 922g. We have federal law in place to prohibit classes of people seen as especially dangerous from owning firearms, except it applies more to stuff like smoking weed or having anxiety than stuff that correlates heavily with being a dangerous person.
Well one obvious reason is that nothing physical is indestructible. Even if your magazine is "locked", there has to be a way to unlock it, and a way to deny the system that requires it to be locked in place while loading from doing so. Another is that magazines are not the only form of reloading your firearms storage of ammo quickly, and are not even really the preferred method in doing so if alternatives are available such as belt feeding
Even if there were a comprehensive list of these firearm loading implements, some innovative mind would certainly come up with a new mechanism of loading quickly and efficiently that might even overcome the hurdles of magazines, something we've seen with FRTs and the legality of machine guns.
So long winded way of saying it's technologically infeasible to prevent loading of a firearm's storage of ammo from occurring quickly. Now there is the logical question, does it affect our rights? The banning of an entire class of firearms not under the "dangerous and unusual" clause would certainly affect our rights. After that we must question, what goal are we actually trying to accomplish, and is this the correct mechanism to do so? We are trying to prevent violent crime, a police issue.
