Does anyone know if Arlen Ness grips will fit the Raider without any mods? I am looking at either the black twisted or black bassani, but want to be sure of a fit before ordering them. If so, what is the part number and where can I find them. Also, does anyone know how bad the vibration gets after you take off the stock grips with the end weights? Thanks! My other option is the Pro One Grips.
