Rare last year first generation .357 Magnum Colt Python with the hollow under lug. This beautiful 4" revolver is in excellent mechanical condition - very smooth with tight lock up and would make a great shooter and should continue to rise in value. Grips are excellent with nice figure and no cracks or wear to the checkering. Bluing is a conservative 95% with most of the wear being holster wear on the end of the lug and the front edges/corners of the cylinder. Bluing is bright, and the bore looks new with a borescope. Comes in original factory box, with original paperwork, original Colt screwdriver, and believe it or not, the original purchase receipt from May 21, 1964 - just over 60 years ago. I purchased from original owner who installed the red front ramp sight from a newer model python ($125) - pistol does come with the original black front blade which was installed on the gun when manufactured. Just knock the two front sight pins out to reinstall. I'm happy to do this for the buyer if they prefer the solid black front ramp as opposed to the red. Both sight blades will come with the pistol.
