My BUG is a S&W Model 360 in 9mm with a partially bobbed hammer. I use the thumb on the hammer method and have never had any issues with either "accidently" cocking it or poor grip. Like everything else, practice makes huge difference. IMO, since revolvers with spurred hammers have been carried for 150+ years with excellent results, I don't think we need to rule them out now.
Since you already have one of the easiest to carry and draw revolvers ever made, why do you want to change? If recoil is an issue, practice with the lightest loads you can find and carry it loaded with the hot stuff. If you ever have to use it you won't notice the pain.
