Lasermax on my lcp max - LaserMax Gripsense Laser

Problems with mine. I returned the first one thinking it was using up batteries too fast. Turns out I found that I was putting it in my pocket carry in my back pocket and when I sat down it would turn on the light. I took quite a bit of trouble trying to figure this out but finally realized it was only eating up batteries when I carried the gun in my back pocket.
Next problem was inside the trigger guard. It had a sharp edge on the plastic that would pinch my finger from time to time. 1st time I went to the range I came back with a big blister on my finger. Finally I just took the unit off my gun and took my jack knife and carved a long smooth edge with SHOULD remedy that situation. I still gotta find a pocket holster that I can replace the Ruger one. I had one other that was worse than the Ruger pocket holster. Not Ruger's fault just that button on the side of the laser would get pushed whenever I sat down.
