Agreed, but P365 FCU fits the legality at this time.
Philosophically, I don’t find it any different than if I said: G19x… with Gen 5 G23 and 22 slides plus G17 and G34 slides… plus mechtech 16 inch conversion…
Basically I’m going to pick the gun with versatility if I’m limited by law.
Honestly, gaming use of pistols is more important for me than self defense use 99.999% of the time, so I would probably pick a CZ75B that I could put a P01 slide on for carry and an SP01 slide for gaming.
But then we are talking about multiple gun configurations which are totally a thing.
