The pistol grip is an open space. Here are a couple of ideas for that space. First and I think most interesting is a device that would hold spare batteries for those who use battery powered optics. It could easily fit two or three spare batteries. Another simpler concept is just a snug fitting plug so the space could be used to hold items (small screwdriver for scope adj. and a battery) and not have them fall out.
I plan to use the space for 2032 battery storage, but my stuff would be functional only and not something nice to look at.
