In all honestly, that would be plenty to keep the gun running for a long time.
That would be a new one on me. It doesn't mean she's wrong, but it represents a change in the way they are at least describing things. I've sent handguns that I bought used back to Beretta before and had them serviced with no issues or questions.Anything else that would require things like removing the barrel-bolt etc. for cleaning requires shipping back to Beretta and usually done at a yearly service. Any disassembly by an end user voids the warranty. I was specifically told to never remove the barrel, polymer mag cover, clamp etc.
