I guess it's about time I contributed something to this thread.
While the reasons that I own guns are many, the order that I usually cite them in goes:
1) Because I can
2) Because I enjoy shooting
3) Self defense (defense of others falls under this)
Of course there are many more reasons, but most of them have already been stated by other members. One that I don't often talk about to non-gunnies is the feeling of absolute...bliss...I have when I leave the range. I'm never more relaxed and calm than when I finish a shooting session. Kinda odd considering the loud noises and sometimes bone-jarring recoil experienced during such sessions, but I'm sure I'm not the only one that just feels GOOD during and after shooting.
I have been in a situation where I needed a gun and did not have one, and it is not something that I intend to relive. I carry every day now. I'm not afraid to go about my day without my gun, but I find it kind of silly to have the ability to carry it but leave it at home instead (like my dad). Other members have brought up the seatbelt analogy, and it is the same thing. You don't put on your seatbelt when you're going to get in a wreck. If you don't use it all the time, it doesn't work.

I think I'll stick to my 1911. Having a gun does not make you invincible (unless you're Steven Segal or some other movie star), but it does give you a MUCH higher chance of surviving a potentially deadly situation than if you are unarmed.
Regarding carrying a gun, I, like many others on this board, have been asked if I was expecting trouble. My response was the same as most others': "If I expect trouble somewhere, I DON'T GO THERE. The gun is for the trouble I DON'T EXPECT."
James, I do have to warn you about something as far as guns go, especially if you plan to read this board with any frequency. Guns are like drugs - very addictive. Before I started reading this board (and The Firing Line and FAL Files before it), I only owned 1 gun (hunting rifle). After hanging out on said boards, my collection has grown to several pistols and longarms. One more word of warning - avoid the picture threads if you want to save money! I should listen to my own advice, but I'm an addict and I love every second of it
