You need this for your colt python combat elite - Kensight Elliason Trijicon Rounded Blade Night Tritium Pistol Night Sight

While my Colt Python Combat Elite came with a Tritium night sight in the front the rear sight was stock with a flat black notch, which made no sense to me as it was next to impossible to line up the front sight in the dark. The Kensight Elliason Trijicon Tritium Rear Sight is the perfect match for my front sight as I now have a working 3-dot night sight set up and it's a better quality sight than the Colt stock issue anyway.
