Even though my grip tape is not here yet for the XD-S, I want to suggest that if you have never tried Talon, you should do so. I prefer the rubber texture over the sand paper, and have it on a couple of Glocks. Makes for better grip on the sub compacts. Just thought I would throw this out here as a first post in this section.
I have used the hogue Handall Jr on my LCP, p3at, and the LC9. I like the Hogue and it works for those that need the extra grip size. I have moved towards the grip tape because it adds to the grip without adding additional size. If I do not need extra size or palm swell, I use the tape. Just that simple.
