Don't have, but want a Para G.I. Expert:
Para USA, High-Quality Handguns: Products
Why?
Because it's a "classic" design.
(The Para Expert has just the right amount of "minor" upgrades to make it a little more "practical" and still suit my tastes for the classic design.)
Edit: I almost forget, Magnum P.I. used to have one, so the "cool factor" of the 1911 is really high for me.
