I let my hand do the selection. I have had just about every kind of grip including ivory, and for “posing”, the fancier ones look nice, but for shooting, I like plain walnut sanded with 220 grit. I also like the checkered plastic grips. What I find useful is the Pearce finger groove insert. On the 191A1, I believe it should be left as simply as possible, and kept low key.
Agreed, but like you I found the Pearce finger grooves a nice improvement along with their side panels.
