I have a KSG arriving this week and looking at decorating it with new furniture. I see some of you mount your lights on top and others on the slide. Is there a tactical or practical advantage/disadvantage to one vs the other? Obviously, if it's on the slide you can potentially flick the light on/off without removing your hand which is advantageous. If it's on top, you're not accidentally hitting it with your hand due to racking or recoil. I imagine when the slide is racked back, the barrel doesn't cut off the light spill too much on the opposite side such that you're having to constantly reacquire your peripheral vision each time? I haven't seen many reviews of the Midwest Industries M-Lok light mount with hand stop. A few of you have it with the IWI light and Magpul vertical grip and that setup looks very appealing to me. Clean and functional.
