How often do you lube your CM9 and how many times do you re-rack the same round?

May be I need to change my process.

Whenever checking or cleaning, I pull the mag and eject the round in the chamber. When finished, I insert magazine, rack one in to the chamber, put the previously racked one back in the magazine, then reinsert mag. Some minor scratching on the brass, but never set back.

That's the proper way to do it. The extractor is designed to pick up the case rim as it comes out of the magazine, not pop over the edge as it slams into the back of the cartridge.
Guns with the external extractors have more travel and generally live longer if you drop a round in the chamber.
Others it's kind of Russian roulette, might work a 1000 times or it might break on the first round, just never know.
Same as shooting lead bullets through a polygonal rifled barrel, it works, many people have fired 100's of lead bullets through them but it could cause issues at any time.
Could blow from over pressure on round 5 or 5005.

I haven't had any set back issues with my cm9. That involves me dry fire practicing almost nightly since I have gotten the pistol a month back. I have rotated out my carry ammo a few times though. When the rounds begin to look scuffed up or discolored I'll just go out back and run the whole mag through the gun.
