kyle663,
Sounds like you may be looking for custom grips rather than shooting type grips. Actually, frame fitting grips would be fairly easy to make for this gun, and those your friend could make for you would be nice...
I'm looking for Pachmayr or Hogue type recoil reducing black rubber or composite grips that would fit my large hands much better and fill the area behind the trigger guard.
In our case, any grips for Virginian Dragoon Pistols seem difficult to find. I wish you luck with your search. What you are looking for could certainly be made by a good craftsman...
