I have 2 surefire 952V weapon lights that I bought used at a gun shop about 8 years ago. I’ve noticed here lately that the flicker when bumped, whether I use the pressure pads or the rear mounted button (thought it may have been a wiring issue). I’ve read recently of guys having luck with surefire swapping them out with the new version, but I’ve also read about them saying F you and kept them since the SN came back .gov. The latter part is what concerns me, even though I did acquire them legitimately on my end, but have no idea where they originated (the gun shop is located an hour away from ft Knox and Campbell).
Has anyone else had luck with having these issues taken care of?
