I'll carry the biggest thing I can, if I can keep my 1911 around I do, other wise Glock 22(.40), failing that, Sig 239(9mm),or Walther PPK/S (.380), and if nothing else will work, beretta 21a in .22.
To be honest though, I carry my Glock 22 openly most of the time (People get REALLY anxious with the 1911 in cond. 1, it's rough enough with the glock) Here in KY you don't need a permit and can go places that Concealed carry is illegal. I do get some comments, and alot of stares, but gotta do what we gotta do.
