I found a very interesting piece of work posted by Dave Workman from the Congressional Research Service titled, Gun Control Legislation. It describes what congress could try to enact in the way of "gun control". Unfortunately there was nothing in there about achieving better trigger control or sight alignment. It did have a nice recap of recent history and current regulations though, it's definitely worth a read if your involved in the rights movement.
I really do need to get better at making regular entries and hopefully things will slow down some and I will post more often.
