I inow **** does it. I have 2 of them. I got the wrong size and if I keep my heads, I will get 1/2 put on. I was wondering if any other company did this a bit cheaper? I am contemplating selling them as i am playing with the aG 100 right now but I have always come back to them so I was thinking of changing the grip size to 1/2 and keeping them. I like the **** wilson shaped pallets that they put on. just was wondering if there was another company. Heat sleves are not an option.
