I'm having trouble seeing why this matters. Most of them don't provide a particularly large tactical advantage, they just make it more comfortable to shoot in low light. A muzzle brake, however, I could see being a more restricted feature, but even then, they're heavily used in competition shooting.
Personally, I don't need more than 8 rounds for 'home defense' because I am not a ****ing moron who would use a high powered rifle or even a pistol inside a house built out of drywall. I have a shotgun with 000 buckshot in my closet. Even duck hunting guns don't tend to have much larger magazines. With a pistol outside of the home, if I had my anxiety under control enough to carry mine, I can reload so fast, even from concealment, that having two ten round magazines instead of a 10-16 round magazine is hardly a difference. I can train a 110 pound girl who has never touched a gun to do the same thing.
I know it's cool to think that the cops can shoot the bad guy while he is reloading, but reality doesn't consistently work like television shows. It offers no assured advantage to someone responding to an active shooter in an unknown environment to assume that you can get them when they reload. Especially since bad guys tend to travel in packs. (Insert 'BUT ALL THESE LONE MASS SHOOTERS!') You know what does help though? Solid training and a well made weapon. But what helps even more is effective GSW and shock treatment for victims after the crazy has been shot by the police, themselves, or The Punisher.
Fortunately, I also have much more sensible home defense features like locked doors, windows, and a habit of not obliviously opening the door after 10 if I am not expecting someone. I also have the common sense to move away from gunfire unless I am by myself. In which case, I totes have a responsibility to investigate.
But in the end, I want my 30 round magazines because I like going out to the desert and shooting at targets. I am used to 30 round magazines. They are more fun, and I like them. And since it is highly likely that I will only ever use any of my firearms for shooting at paper grocery bags stapled to sticks, I would really appreciate it if we could focus on treating the underlying causes of gun violence instead of wasting precious administrative calories on deciding whether or not a pistol grip and a flash hider will allow a shooter to kill .5 more people.
