I guess that I am opening myself up to ridicule, but I have a Gen 4 17 with the same finish and love the thing. It cleans up easier that the normal Glock finish and is more aesthetically pleasing in my eyes. For sights, I added a 10 8 U notch rear with a Dawson fiber optic front. I don’t buy that the finish increases the relability but mine has been 100% with over 1,200 rounds down the pipe.
