If (God Forbid), you were to carry one; which one would you carry and why? Also, what would be your choice of platform?

I�ve always had a fascination with the little threaded barrel Beretta 21�s. I had a 21 the year it came out in .25 ACP (don�t ask), and I have to say, that little gun shot FAR better than it had any right to. I could EASILY make upper chest hits at 15 yards, and more often than not, hit an upper chest at 25 yards. Downright decent little pistol; for a Mousegun.
