USED XS Sight Systems Standard Dot Sight Tritium Green S&W J Frame/Ruger SP101/Fixed Rear

USED XS Sight Systems Standard Dot Sight Tritium Green S&W J Frame/Ruger SP101/Fixed Rear. Precision machined in Fort Worth TX XS Sights feature a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. Standard Dot is larger than most fronts to be seen under stress but covers less of the target than the Big Dot. The increased surface area of the convex dot increases light absorption intensifying the charge of the glow properties of the dot. Day-Light Half-Light or Low-Light place the bottom of the dot in the bottom of the sight channel and center the dot over your target within 15 yards. Outside Diameter Standard Dot 0.140"; fits in common holsters. Sight pre-drilled and comes with new retaining pin and thread locker; gunsmith installation recommended. Fits S&W J-Frame with pinned front sight and Ruger SP101 with a fixed rear. Installation requires a drill press to drill the retaining pin hole in sight body.
