I believe I read something to that effect, that a little light oil on the rotating barrel assembly will go a long way. This could mean just a very small drop every thousand rounds or so. After the initial 100 or so I cleaned it and could not even tell it had been fired.
I clean mine after every session, only in the few hundred so far, so cannot attest to running it diry, but has fed cheap and reloads without fail. Only one bullet reload that was severely out of spec - but not the gun.
The slide and rotating barell are pretty robust, and that is maybe a factor in its good quality and reliability.
I would not worry at all.
