Gun Dog i have the true glow n/s on my 36 and they work out very well, my 17 has standard glock n/s on it , my 36 is green front and yellow rear i really like the collar contrast. as far as lights go i prefer a handheld light i believe i can be more effective this way than a gun mounted light, how ever having one set up for the head board with a light for those with lesser skills is i think a good way to go. not saying i am right but for me it works.
