My quest for a small, simple, reliable GR grip has led me to experimentation with "finger loops". After a couple of not so useful designs like this one
I tried this approach
and it was almost good but the finger loop/ring did not rotate enough to be comfortable; the good part was that the GR was almost "glued" to my hand.
So today I made this "proof of concept" and I kind of like it. Good grip/control and access to buttons. Now I just need to figure out how to make it out of pretty leather and make it easily attachable and removable.
Would appreciate any constructive advice.
