Nobody reasonable should be against registration of guns. The registration should include forensics to make murders easier to solve.
I don't really agree with limits on the number of guns you can own. I don't think anyone should be able to get a silencer, a fully automatic gun, or a tool to make the gun fire faster. That said, I don't think these guns are causing any major problems in the US and certainly won't lose sleep if they don't get banned.
Also, you should have to pass a target practice test to get a license and eye exams every few years after to keep it.
