Getting the recoil spring out is the hardest part, easy to do with a small screwdriver. If you do like it says in the manual and you have a tight fitting spring assembly, you'll bend the spring guide(I did at least).
On the bright side though, you shouldn't have to disassemble it often since the action is so easy to access. I just scrub the breech face with a toothbrush and oil all the mating surfaces on the top and bottom of the slide and it's good to go. The soot doesn't really have anywhere else to stick with this design.
