The overall length of the 7.62x25 is too great for the magazine and slide stroke of any current model pistol. I really doubt anybody is going to tool up for a new gun so people can shoot cheap Commie surplus ammunition.
Maybe I'm remembering incorrectly, but I thought I remember reading in Patrick Sweeney's 1911 book that had owned or at least shot 1911 re-chambered for 7.62x25.
