The slide does have to be taken off. I'm sure there is some special wrench that they have to use on the slide but I have took a metal rod that fits the holes and run it through them to break it loose to unscrew it same for tightening it back up. Oh yeah don't forget to check the o-ring and to lube it when putting it back together.
