If I was transfering an unloaded firearm into my house from my vehicle and, what I percieve as a nut or BG, comes charging at me, I may very well point my unloaded firearm anyway. But in reality since I have a CCW when I am transferring weapons (unloaded) I'm always loaded up with a sidearm. This is too bad. Very unfortunate for both parties. I don't like to advertise my weapons when transporting them to and from my vehicle but I don't necassarily think it's wrong either. I just don't think it's very smart.
Look I like glocks. I've owned Sig's, HK's, 1911's, S&W, and other fine pistols but Glocks have been a favorite for me. Handguns without safeties are not dangerous. Idiots are dangerous.
