For my Mossberg 500, I have a side saddle light mount for a mini-maglite. Now I have acquired a pressure switch designed to control the light with simple finger pressure. The switch is on a coiled line to the mag-lite, and is attached to the shotgun by means of a velcro fastener with sticky glue on the back. My question: where is the best place on the shotgun to mount the pressure switch? I am right handed. Thanks.
