Try shooting your DS with the factory wood grips first. Those Gen 3 grips work well for many. If you decide not to use them be sure to carefully save the wood. They are pretty pricey to replace.
I'm trying to learn to like those wood grips, but it's a slow process. I've thought about trying a Tyler T-grip, but I've read that dealing with the company is a nightmare. Anyone know if that is still the case?
