I have an as new Streamlight, use left or right side control, momentary / off / on. Set up for use with Glock or other Picatinney type rail. Never used a set of batteries through it. It is as new as you can get.
Looking for ESEE-3 or Laser Strike, BM Ritter in M2, M4, M390, prefer large in M390. Let me know what you have and we can go from there. We can work out a trade as needed to make it fair for both of us.
