XTrooper, I am not certain what problem is solved with the PS grip either. I had thought perhaps the designer was trying to make something similar to a revolver grip, but it certainly didn’t work out that way.
I currently have Hogues on my 1076 and 4566. I am going to put the arched grip on one of them for the next range trip. I want to see if fast double/triple taps are better with one or the other. I have never been able to convince myself, a little shoot-off may do it.

I have never seen anything written about what sort of hand shape (or mental hang-up?) causes us to pick the flat or arched mainspring housing. More study is needed; I should apply for a Government grant.
