Especially since what feels to be the massive current and ongoing LEO shift from .40 to 9mm. I just don't see the basic appeal of going back to a higher pressure, harder recoiling cartridge (and one with significant penetration/overpenetration...) characteristics. And then factor in caliber change/equipment change expenses....I'm not seeing it. The role/niche Apex seems to be aiming for would strike me as being covered better by rifles-which are presumptively already on hand in many cases.
