"Guns for Hands" has nothing to do with gun control in the United States. It's about controlling suicidal thoughts. Pointing our "guns" at something other than ourselves ("I simply tell them they should shoot at this, simply suggest my chest") in this case, Tyler is offering up himself. It's about not hurting yourself.
And the lyric "Cause you all have guns, and you never put the safety on" is in reference to mass depression.
They're a little over hyped where I'm from, mainly just cause they're from Ohio, but the album isn't bad. I find it funny how you mention that "House of Gold" is filler but it ended up being a single that's gotten decent radio play in Cincinnati.
