Definitely go with the VZs, they will be the most common to be on members handguns. And as mentioned, any texture from smooth to bastard rasps. You could ask members local to you to fondle,,,,, err, ah,,,,, feel there grips to see what texture suites you before ordering so that you buy the perfect texture the first time instead of ending up with several sets that are not the perfect ones for you.
And when you find the texture that you want, go to the “Wanted” section in the trading post and ask the members what you are looking for and some of us might have the ones you are looking for.
