Sirs, I would like to ask direction where i could get a sight removal tool for the hs2000 so that i could install a ATS sight for it. I have already removed everything from the slide and i still cant seem to see where the screws are for the rear sights. How am i going to remove the rear sights of the hs? Does the tool also apply to the rear sights or i just need to tap it out of place and replace it with the new one? Your advices would be very helpful. Thank you.
