breakdown how far?
Removing the barrel and bolt/hammer assembly isn't a big deal. I have done it regularly. Taking apart the trigger I have not tried and have no reason to do.
If you go as far as barrel and bolt/assembly make sure you look at how they fit together when you take them out. The only thing I found a bit tricky is getting the hammer back across the release(/) it takes a bit of wriggling to do and I don't know how to describe it in words.
