My wife has the Shield 9mm for her CC. We've equipped her Shield with the Lasermax Centerfire Laser CF-Shield. After taking it to the range after about 50 rounds or so the laser started dimming out. It has a fresh battery so it appears that it was due to the recoil possibly jarring the connection to the battery loose. Although I'm not completely certain this was the cause just a guess. Have any of you ever experienced this with the Lasermax? If so how did you resolve this issue? Hoping we can fix this without sending it in.
