My humble opinion is you have the light in the right spot. More specifically, you have the actuation button in just the right spot. I'd prefer the light under the mag to minimize shadow to the right but until someone makes a dogleg shaped light one must make a decision. Having the button in the right spot is of paramount importance.
Thanks opinions can be very helpful.
Yes, I can operate the light from the forearm with minor hand movement, so that seems right to me. In the house I haven’t noticed much if any shadowing so far.
As for the sling, it’s just for field trips, so not always on the gun ... I just get bugged a little by things that don’t work or look right.
I’ll get it figured out with something.
