I didn't think that machine guns were illegal at all, but they did put a limit on the magazine size in Colorado, I think their looking to overturn that decision. I'm not really into guns, although we own a few. Neither of us are into anything but some target practice out in the backwoods, and protection, of course. Neither of us have a concealed carry, but if we feel the need for it in the future, we will be doing that too.
I thought that silencers were illegal, but I know that people can make their own if they really want to. We have never used our firearms for any illegal activity, and thankfully have never had to use them for self defense either. But I'd rather have them and not need them, than not have them and need them. I do understand the people who choose not to own guns at all, and who are against them, that's their choice and I respect it.
