Tactical Rifleman reviews the Crimson Trace Laser Guard Pro which they consider to be the best light/laser for the Glock Pistol... "You guys all know that I preach mastering your Iron Sights. You also know that I always prefer to have a weapon mounted light, whether rifle or pistol.  So, when Glock asked me to try out their new Glock-43; I knew I needed to find a light for it. Hunting around, I heard that Crimson Trace had a 'new' pistol light for the G-42/43.
