I'm having a hard time finding some plain walnut (no medallion) grips that fit my New Vaquero.Anyone got a suggestion ?

check ebay and gunbroker. Altamont grips, Arizona grips, Ajax grips, lots of places to look.

Looked at all of em' with no luck yet.Found some on ebay but returned them because the fit was horrible.
