scratchy panels on my G3C grips were rubbing a raw spot on my side. i had some GT 5000 grip tape and cut a couple of pieces to cover the panels. didn't try to make them fit perfectly, but they're not an eyesore. hesitated posting this, as it's such an obvious simple fix.
Did you notice no hair grew where the grip rubbed against your side ? Makes a great depilatory for the ladys I would imagine ? I use the Hougue Handall Jr.Slip on ,works great ! Beavertail slip on filled up my hand so which ever works for you is an in-expensive fix !
