Watched the videos for the USP and the P30's and the one video said it would work on a P2000 also. Went to reassemble and I can not figure out where the elbow spring goes. I can find no information for the P2000 other than it is the only one with that spring. Can't figure out how to install the piece that goes in with the hammer and uses the hammer pin. Does anyone have a write-up or a armorer manual PDF? Before anyone says I shouldn't have done this, I voided the warranty or all I needed to do was use some compressed air, I am glad I did. I used Break-Free and alcohol regularly but when I got it apart it was so gunked up it was nasty.
