I have an Inforce WML that I swap between my AR and 590. On the AR I mount it at 12:00 so I can activate it with either hand, and on the 590 I tried mounting it at 6:00 but found it too awkward to reliably activate because of the angle of the button, so I moved it to 9:00 so I can work the pump with my left hand and use left thumb to activate the light. It works well in that position but I think it would be better to have it at 6:00 for less barrel shadow and ambidextrous activation. I checked out some of the integrated forend lights like Surefire but they are expensive and heavy. Has anyone tried mounting something like the Streamlight Protac at 6:00 with a pressure switch at 3:00 or 9:00? I figured this would work well but after googling for a while haven't found any pictures of this setup on a shotgun.
