I don't know about any "promises" but the government did, in fact, put out a proposal for a bid on pretty much replacing the 9mm M9 with .45 pistols...something like several hundred thousand if I recall correctly.

That proposal has since been killed and the decision made to stay with the M9 for most troops as I understand it, but I have no "proof" that such is the case. There apparently IS still a request for a bid / test for a .45acp pistol for Spec. Ops. troops which would account for about 50,000 or fewer handguns, and this one is being entered by Beretta, Sig, H&K and maybe S&W...again, so far as I know...none of them have called me and given me the latest news!

This contract has not yet been awarded.

So, your info sounds like typical gunshop rumor after several guys read parts of what is really happening
