You'd be right Doug, with the Colt DA 45 on the barrel. Good looking revolver.Now you can't just post a pic like that without a description! Is that an old, chopped down Colt 1917? Looks like a neat bellygun, for sure!
S&W 340PD with CTC grips. Since this pic was taken it has been to Cylinder & Slide for their carry package and a tritium insert (front sight).
