At the end of the day, converting a 10mm pistol to 9x23 isn't super cheap and simple. There's a barrel change, mag swap (or modification), and for reliability i would want a slide dedicated.
FWIW 9x23 is capable of 357 mag ballistics with all bullet weights, in a pistol with roughly the same dimensional capacity as 9mm. Glock should partner with Winchester and be all over this. There would be a market for true, full 357 mag capabilities in a service sized high capacity semi-auto.
Standard 357 SIG is close, and 357 SIG loads from Underwood, Double Tap and Buffalo Bore equal the 357 mag / 9X23.
