I am quite pleased with the factory engraved firearms that I own, but the Factory is not THE engraving standard

There are literally hundreds, perhaps thousands of engravers in America that can do as good a job or better and usually at a better price and/or faster turnaround

Go look at the FEGA website. The Firearms Engravers Guild of America will have samples from MANY engravers for you to pick from. Perhaps you will even find one in your own state.
