My son has a new S&W Shield in 9m/m and likes the pistol just fine. He bought a brand new combo laser/light for it and is having a problem with this Streamlight TLR 6. The laser beam and light work just fine until the battery compartment lid is closed completely. If the lid is NOT completely closed, the light will function perfectly but not if the battery door compartment lid is snapped completely shut. Anyone else here have any such problem - IF anyone else even has a similar Streamlight Model TLR 6. I presume he will have to contact the Streamlight direct for warranty work but wonder what the chances are that they just make a total exchange???
