Hello Guys. This is a pic of two of my guns built for fast draw. They have aluminum barrels with a rifled steel insert. Also have adjustable hammer stop blocks for perfect timing. Profile slimmed down to lose weight and ease drawing from holster. One gun has a fanning hammer on it and the other has a thumb draw hammer. The cylinders started out as .357 and were bored out to .45 cal. These guns were made by Bob Graham in Texas.
