"Hey, guys, let's make a pistol that adds a bunch of extra mechanical complexity while negating one of the principle advantages of 9x19mm, namely dirt cheap training ammo, all for the dubious benefit of adding a possible 25-to-50 feet per second of muzzle velocity!"
I mean, if you want one as a range toy-slash-safe queen simply for the mechanical curiosity because you're an absolute gun nerd, that's understandable, but I'm pretty much of the opinion that it's a fundamentally unserious choice as an actual life-saving tool.
