UM Tactical will be showcasing their UM3 Sight Mount at the SHOT Show 2019... "UM Tactical has created a universal sight mount that will fit all pistols with a 1913 picatinny rail. Although there are many sight mounts that exist, the UM3 is unique. It can be mounted or removed from your firearm in under 30 seconds without the use of tools or gunsmithing. Once your optic has been sighted in, the mount can be taken on and off and will still hold zero!
