I have to wonder why the US didn't go with the BHP.
Well, when the dust settled, things sorted out, and the Beretta and SIG were top ranked. They had the features and the design integrity, ie, both companies had been making that style of firearm in large quantities to specification. American makers didn't get that kind of support previously because the US Gov. didn't buy any for a long time. It was all civilian and LEO sales up to that point. No .gov contracts much.
Better to ask why Beretta over SIG? Consider - the military gets one firearm for use by a number of troops who carry them in figurehead positions and very little combat action. The other group - CID, NCIS, USCG, OSI, SEALS - gets to use a pistol in daily carry as a duty gun where it's important.
Another aspect - whether it did or didn't happen is moot - Italy has a number of our bases on it's soil, including a parachute regiment and refueling station for the Mediterranean fleet. It was rumored at the time by military sources in the know that the Italian government did use some back channels to point out our dependency.
What I find interesting about all the gnashing of teeth is the angst that Beretta was ever chosen - when the reality is that the Armed Forces don't use pistols to any great degree at all. The primary weapon is the M16 and it's variants. Pistols are a sideshow for the MP and Officers when they are not in a combat zone. Even the Marine Corp requires the M16/M4 as the issue weapon up to the rank of Lieutenant Colonel.
If you are in combat arms on hostile ground having a pistol alone is ranked as being in a bad tactical situation. The rifle is preferred - even when raiding Pakistani penthouses. Pistols are a worst case backup when the rifle somehow meets an unfortunate malfunction that prevents immediate remediation. It's an OMG moment - and few want to be stuck with just a pistol right then.
Better than nothing and it fits when working non combat life when a symbol of authority is it's biggest job. The Beretta gets that job done, and the users with an actual real world need get the SIG.
I have no problems with that. I once owned a 92F working Rent a Cop years ago, now I have a SIG as a compact CCW. One for show, the other for go. Of course, the primary is a AR15.
Each has it's place, don't get worked up about it. The right decisions were made and the guns were assigned as they were needed. It's all good.
