You can get grips for the Gaucho, at Dixie Gun works, PN WP 7604. They are rosewood, but they will require fitting, as they come quite large, also order the SP 0507 screw and nut, for the grips, as the one that comes with the grips is not too nice. I had to fit them to my Gauchos, and they came out real nice. It's not that bad of a job.
Also , you can get grips for the Gaucho at gungrips , I am not familiar with their stuff.
Dixies grips and screws are around $40.00, gungrips are about the same.
Keep those Gauchos going, they are good pistolas. Mine are polished stainless, in .357 cal. I wont get rid of mine.
