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.

I own a .45 1911, FnH FNS .40, and a Diamondback Firearms M4. Looking in to buying a Rock River .308 LAiR with an aluminum barrel.
