To check for/ remove gunk, grime, gum, corrosion. To clean, lubricate, etc. The usual ‘owner maintenance’ of a fine firearm.
I have no intent of taking apart a trigger mechanism, etc. This was just to ascertain what is the right owner maintenance to perform, and how to do it.
No different than what I would do with any of my other long guns.
If the action works fine, no need to disassemble. Leave it alone. Unless you know the reputation of the gunsmith to be excellent, I wouldn’t have him mess with it either.
