I got a call from the dealer.

“We got you Baikal back from the gunsmith and he told us that it was wery dry and insuffiently lubed and mostly because of that the mechanism was very tense”

O_o ?

Did I not explain how the gun was intentionally left dry so that the gunsmith could inspect it and lube as he wishes.

“Yeah, well the gunsmith told that that the lack of lubricant was the only thing he could find and there is nothing to do”

So did he tested it? Does the gun work now?

(long pause) “we could send the gun to importer so their gunsmith could take a look at ti, but we called them and their stand is that because you’ve changed the internal components of the gun it’s out of warranty”

What? I have not changed any of the internal components. Unless you’re counting magazine spring and follower, but it does not take a rocket scientist (or trusted gunsmith) to tell that they’re not the reason that the slide is not moving enough for the bolt & ejector to pull the shell against the extractor.
I told them that all internal components are original and I’ve packed the original magazine spring, magazine cap and follower there if they would like to test the gun with them. Please send the gun to importer.

“Umgh, it might take long for them to react on this, no schedule when we might get the gun back”

I could barely restrain my self telling them that it’s taking also a long time to reload semiautomatic shotgun by hand so actually I don’t mind if repair takes little longer as long as the gun would reload itself.

Now my Baikal is on it’s way to importers gunsmith. I still can’t help thinking about the full auto Baikal the dealer had. Why my gun could not break to full auto? That would have been such fun, and maybe slightly illegal’ish?
