I am getting some Truglo TFO's installed on my XD-9 service. I cant wait, it should be sweet. I read one post after doing a search that said not to use gun cleaner on the sites. I use Hoppes elite gun cleaner and CLP breakfree for oiling. Do you have to avoid touching the sights with these products like its the plague? If you get any on it, do you wipe it off quickly and will it be fine? Thanks guys.
