Check out Altamont Boot Grips. I would go with Checkered Finger Groove Rosewood Boot Grips. Also add the S&W Medallions for an extra $10, you will be glad you did.
I have the Walnut version on my 310NG. Mine are S&W by Altamont, which do not come with Medallions.
I have the Checkered Finger Groove Rosewood Boot Grips on my 315NG and 3" 66-2.
The Medallions are an option when you order direct from Altamont, besides the grips being cheaper.
