I have an older Remington 870. It is an ex-police shotgun. It has a wood stock and plastic recoil pad. The pad is curved on the end that meets the stock as well as the end that engages the shoulder. I would like to get a cushiony, rubber recoil pad. All those I have seen have a straight back end that meets the stock, and will not fit this firearm. Does anyone know where I might find a pad that has a curve to both sides. I contacted Remington and am still awaiting their answer. Thanks
