Battery scare - Crimson Trace Smith and Wesson J-Frame Revolver Round Butt Lasergrip Green Laser Sight

After I put these on my j frame I noticed some intermittent failure to illuminate events. I admit I was nervous because I KNOW crimson trace reputation is stellar. After reading the instructions closer I realized I didn't install the copper plate correctly so it was all my fault. There is a pair of tabs on the bottom that have housing groves they go in before the screw goes in. Now I know I can count on this thing to function every single time. Only reason I gave 4 stars is for how hard my heart was beating before I knew it was my bad. For sure recommend to anyone. Even fits in my leather holster no problem.
