Thanks for the idea Sportsterguy. And jughead440 - couldn't thank you more for posting an example of that kind of work done right after Sportsterguy's post. I was wondering how the finish would look after sanding it - looks like a non-problem. Or did you do something to finish it?
I'm going to have to go after mine - those squared of edges in the finger grooves are my only complaint.
And ... one thing I probably should have mentioned in the original post - the '-6', is a RB grip frame. The grips on mine are the Ahrend's RB->SB conversion.
