I have a G22 RTF2 with gills and I am loving it so far. The grip is amazing both on the slide and frame. I have had a few strange questions about the gills.
Q-Why would you get that done? A-It came that way! has been a common one.

Only down side I see is the frame texture will wear down faster, but I will wait and see.
