An exploded diagram is the *only* thing of any value at all in the user manual that came with the gun but it tells me nothing about the proper sequence of disassembly steps. From my experience with other firearms, electromechanical equipment, appliances, autos, etc. I know that some things absolutely require a certain sequence be followed to get it apart or back together without buggering something up. I also know enough to get the proper info and tools if I don't already have them before I start to work on an expensive item but so far the info on this one is eluding me...it is a CZ Hammer Coach gun which was built by the Turkish manufacturer Huglu...yeah, I know, but they seem to be the only source for new coach guns other than the Russian and Chinese varieties which do not appeal to me. In my case the fit, finish, and functionality are fine, quite good in fact so, so why do I want to get into it? That would be because at some point I will want to get into its innards for cleaning and lubing and I do not want to wait until that time to try to find the info to do so.
