I'm trying not to be really stupid here, but I see a pressure switch on the right grip panel that pushes only a fine wire/solder point to the assumed, stored battery in its compartment. Then I see two conductors travel up and through the frame, on the side plate side, under the adjustable rear sight and then to a "channel" from the front of the rear sight, to the front sight? So does one conductor drop off some place? What's lighted, the front sight only & if so, why exit the grip frame with a second conductor instead of grounding it locally at the grip frame? Is the rear sight lighted too? My head hurts.
