Hey guys. I have a Glock 45, model 21 that has an Applied Laser Systems laser mounted on the trigger guard. The wiring goes inside the trigger guard and comes out with a panel down the grip. The laser is initiated when you squeeze the grip. I need to figure out how to change the battery, but have no clue. The battery is not in the grip part. I took the laser off of the trigger guard and can't seem to get into the laser to see if the battery is in there. I took it into Cabela's and 88 Tactical and they both said they have no clue and have never seen anything like it. Unfortunately the laser manufacturer went belly up a long time ago. Anyone have any ideas? Picture to follow...
