The rear corners of the RH grip and the MSH dig into the meat of my thumb. So a rounded MSH and grips, I think, would be the ticket.
That sounds borderline cup and saucer.
You could identify the maker - or at least, differentiate between a Kimber and the rest - using only your senses of touch and hearing?
I can tell you by touch and trigger the difference between any of my customs VS a Kimber. I could also tell the difference between my Les Baer and any custom out there EXCEPT maybe a Springer Pro. Those that own a Baer will understand. I can also hear the difference between a C&S trigger group being dry fired opposed to others. But, who cares?
