Yes it is off - but the hammer is down - that is decocked AND it is empty. How do you know that? The FNX has a neat little loaded chamber indicator. The tip of the extractor will poke out with a red dot if it was loaded.
(Rule #1 kids, treat all guns as if they are loaded, always point in a safe direction, always check if it is loaded when you pick it up.)
So no, not violating safety rules, as one doesn’t generally keep an unloaded gun on safety, and many guns can’t be put on safety unless cocked (e.g. the 1911 and AR-15)
