Rumor has it pretty soon. Springfield hasn't told us when we should expect a few however. Honestly if you get a chance try the .45 out. I was surprised at how soft it shot for a pocket size poly .45. I am a big fan of the 9mm round don't get me wrong, but with such a limited capacity pocket gun I feel better with a larger round.
It really didn't have much more recoil than the Kahr PM-9 I used to own.
