Wow, well over 200 views, yet no one has weighed in with *any* opinion...
For what it's worth, I plan to disassemble the Makarov according to the following instructions:

If the feedback is "bad idea!", then I'll probably just lube and oil and metal-to-metal areas on the gun.
If the consensus opinion is that bore compound won't harm the internals, I'll probably use some compound where the hammer, sear, and hammer bar touch each other, then spend a weekend dry firing the gun with some 9x18 Snap Caps.
