The mounting of Red-Dot Optics to handguns is a simple task that's become even more simple when you own a sight adapter plate. Here comes TruGlo offering Pistol Red Dot Sight Adapter, which can be used to convert the mount styles between RMR, Leupold Deltapoint Pro, and 4-Post Mounting Systems. The first thing you need to figure out is what type of mount compatibility the pistol and red dot sight require. And after that choose the adapter plate that allows you to get advantage of the latest optic technology regardless of the footprint.
