I've thought of that too. In order to be protected it's going to have to remain centerline. The way they seem to do if for auto's is to attach the wire to a ridgid support, since those supports are model specific I have to wait until I place the light on the weapon to find out the distance, if there is one that will already work, there's my solution, if I have to use the loose wire, then I get to apply ingenuity.
I'll let you know how it goes.
