I wear a size XL glove. As others have stated the Troopers are for larger hands. I purchased a pair and in spite of having rather large hands I found them way too big to shoot the N Frame in DA mode. Shooting it in single action was fine, but most of the time I shoot guns like the M29 in DA mode. I ended up selling them to a guy with XXL hands.
The Ropers fit my hand much better, and I have observed that they fit most people's hands better. That said, I picked up a set of Herretts Detective grips for a 2.5" M19 and they are absolutely perfection. I intend in the future to pick up a set of Detective grips for one of my N Frames, as I have never found a better grip anywhere.
It is my understanding that Rod Herrett has retired and has sold the place. I have not spoken to him for a bit, and I don't know who the new owners are, but they do have a new website up, so that is a very good thing, as the old one was extremely dated.
Here are the Herretts Detectives:
