I went to Home Depot, in the section where they sell stuff for decks. I looked at the grip tape they sell for steps. They had sandpaper type, and rubbery type. This looks and feels like the same stuff the stick on grips you buy online is made from.
Othewise, I like the Hogue and Pachmeyer about the same. The Hogue gives a hint of a palm swell, but the Pachmeyer is more streamlined. Both will need to be installed (or modified in a way) as to avoid contact with the grip safety.
When I had the Pachmeyer on mine, instead of cutting out a spot for the safety, I just put it on upside down. It worked great that way.
