You know, unlike some people, when it comes to the second amendment, I don't believe in "certain, inalienable rights." I do believe that we, as Americans, do have the right to own firearms. But along with that right, I believe that we have a responsibility to carry ourselves in a safe manner while under arms. I do believe that intelligent gun control is a good thing. I also believe that there should be a law that says that if you do stupid stuff with firearms that endangers others, they should be taken from you. "Be safe or go home," pretty much.
Now how can you be safe with firearms?
First, don't buy a glock. There is no safety on almost all glocks. I believe that owning safe firearms is the first step. Yes, all of them are dangerous, but they should only be dangerous when the intent is to fire.
Second, if someone knows you have a gun, you're doing it wrong.
Third, Just like cars, some people think bigger is better, while others prefer compacts over suvs. Find what you can drive well and are comfortable with and carry that. Personally, I carry a .45. I can handle it and find it more accurate in my hands than my 9mm.
Fourth and finally, just don't be dumb. Don't point your gun at someone you don't plan on shooting. Don't "shoot to wound" because that's how most misses occur. And don't let your emotions end the life of someone who wasn't a threat.
