I stopped shooting my 22/45 because it was such a PITA to re-assemble. Had my son out shooting and used the 22/45 to orientate him to shooting a semi-auto pistol. Dreaded cleaning it but did it anyways. I was amazed that it went back together without a hitch. I got it back to together and thought that I couldn't have gotten that easy. I wish I could remember what the heck I had done. I think it had to do with what hatidua said.
