I have carried a Fitz GF Gunfighter grip on my model 60 as my off duty weapon as a Marshal and while retired with my CCW.
It was designed for police off duty weapons with the back strap left exposed to not shorten the trigger finger for smaller hands and some added below the frame for bigger hands. It does not hang up on clothes like a rubber grip and is designed for an inside belt holster and for orienting for firing right or left handed around barricades or two handed in the dark from the waist.
Many officers I taught with this grip in my classes were extremely accurate at the 7 yard line in the dark.
GO to the fitz site and ask about it while they last.
