The Crimson Trace CT RAD Dovetail Mounting Kit lets you mount your best-in-class red dot on your trusted Smith & Wesson pistol. No need for expensive gunsmith work to cut your slide, this kit uses the existing dovetail notch to secure the low profile adapter plate to the slide. Then simply attach your CT RAD, CT RAD PRO, CT RAD MICRO or CT RAD MICRO PRO to that adapter plate. The Dovetail Mounting Kit is compatible with some of the most popular Smith & Wesson pistols on the market today. Now you can use the best red dots on the market with the pistol you have trusted for years. At Crimson Trace failure is not an option.
