Thanks, Ken. Recently Jim Davis mentioned in a thread somewhere or other that he suspected that COM (or DOM) might have been the outsource company for the barrels alone....hence the marking on the barrel only. I thought perhaps the markings on the frame might perhaps ring a bell of some other manufacturer's M.O. but you could be right; they may have manufactured the entire gun. At any rate, while not the highest quality gun, it is an unusual piece and I am quite proud to own it. Thanks for your input! Karma headed your way!
