Cthulhu, you do speak the truth, Sir. However, I would turn your attention to the 1911 style frames used in the LAR Grizzly. If you can load .357 Magnum rounds into one, I am sure you can do X25 with no problems. X25 isnt that much longer than 10MM... it can be done, and done in a manner that wouldn't be too unweildy.
Thinking about this further, I think the ideal platform for such a gun... it is not the 1911. That was an oversight making that suggestion. The proper platform needs to be a gun that has an already outstanding level of accuracy... and to me, that means the CZ-97B. The 97 that I owned was the most accurate handgun that I had ever owned or even fired. Period. Building a 7.62X25 from a 97 would yeild a handgun capable of accuracy that would be just unbelievable.
Given the flat shooting balistics of the round, matched with such as accurate platform... You would be sweeping those long range steel rams like silly... you might be punching holes in them too... *oops*
