If so, which one(s) do you have?
Personally, I own a Glock 23, although I don't actually have it at home with me because I'm a college renter and my landlord doesn't allow weapons on the property. It's a reliable home defense pistol that you can easily carry concealed (although I never have) and it's a good value price-wise.

No, we don't have guns in my country which i'm glad for. That way if i get lost when hiking or whatever i can approach any house i see without fear of being blasted into oblivion by some paranoid lunatic.
