How is the grip for you? Do you plan to keep the gun or sell down the road? I'm guessing you plan to keep with all the slide work done. If you have trouble with the grip or feel like you need some texture to grip it better, stippling may be a good option. As others have stated you could always start with the backstrap as that can be replaced. The frame on the other hand isn't as easily replaced. If you decide to stipple I would spend the money and get someone really good to do the work, that way your less likely to be unhappy with the results. Diversified Firearms Concepts, Boresight Solutions, or Salient Arms Int. would be the top choices, but be ready to pay for it.
