It is better to redo both grips that way they match perfectly. I spray dollar store oven cleaneron my grips and stocks that need stripped the go over them with 0000 steel wool rinse with water if needed spay any spots you miss and go back over them it takes less time than wood stripers do. Stain what ever color you want and for a nice finish hand rub them with true-oil. I use 3 to 6 coats depending on the amount of shine you want them to have. I like the true-oil because it brings out the natural wood grains.
