I have a Glock tatical light. I was using it in training, with a Glock "simunitions" G19 when it just stopped working. I had just put fresh batteries in that morning. After I removed the light from the gun, the cover over the battery compartment fell off, and I couldn't get to stay closed. Even after changing the batteries, and the bulb, it still wouldn't work. Anyone else have any problems with the Glock Tactical Light
