Funny, I had just started this thread to post that link. DocGKR's post prompted me to look around for more on the FBI program.
The FBI Request for Proposal (RFP) and the XM17 MHS are fascinating contrasts. The FBI seems to very clearly know what they want, and have crafted a narrowly defined RFP that should quickly cut down the playing field to a handful of entrants (if that). Meanwhile, the Army seems to have only the vaguest idea of what they want, even leaving caliber choice open to the manufacturers, and have crafted requirements so broad that it will be difficult to sort the apples from oranges.
