Constantine... I think you can breathe easy regarding the short barrel. Mine hasn't missed a beat, except for a problem that was taken care of by a Colt recall. That probably sounds like faint praise.... what I'm trying to say is that I've had NO problems due to the short barrel. Kind of wish I had sights (other than trench sights) on mine, but for a carry pistol, the trench sights are fine.
OP - awesome looking pistol!
