I really like the LWD qwik-grip, it has no finger grooves like what's found on the Hogue models. It's a bit thicker material and provides a solid hold that doesn't shift side to side while shooting.
For aftermarket stippling, which may be what you're asking for, the two most common are Robar at
www.robarguns.com or Bowie Tactical Concepts
www.bowietacticalconcepts.com. This is a bit pricey and will run probably more than $100 depending on what you want done. Grip reductions, restippling, shaving off the trigger guard hook, many other things can be done to make the weapon more suited to you. Both companies will also do refinishing work and can cut front slide serrations. My Glock 26 is with Bowie right now, and I have had Robar perform work on my pistols before, they're great people.
