As a NATO infantry officer (and great friend of USA) I can only say you hit the nail on the head.
With several missions with hundreds and hundreds of other soldiers I've never really come across situations where a handgun made the difference. Oh well not true. Several dogs have been killed with handguns.
In Iraq I often did hold my pistol (SIG 210) in my hand while being in the passengers seat. Mainly because my M4 would be to hard to swing across and fire forinstance out the drivers window. The main concern was a vehicle coming up on the side and starting shooting. But beside that and also when attending meetings with locals where for political reasons visible weapons was not an option, and therefor I carried conceald, I have never seen handguns needed. Sorry I got side tracked. Any way a handgun, for a soldier, is "nice to have" but not "need", however I would not go in the field without one.
A revolver is not in any way interesting for a soldier!
I know all S&W fans will hate this but a Glock 17 or 19 would be a fine replacement. I'm still speaking as a soldier.
Caliber (9 mm versus .45) is not interesting except from what other allied bring to the battlefield so we can realy on each other when it comes to suplyes (excuse my spelling).
I've carried a M9 for some years now but am still issued the SIG 210, but as a firearms instructor I've managed to "testfire" and carry the M9 domestic, while working in the army with securitymatters. It is a fine servicepistol and it does the job (nothing else can be asked). Personaly I would pick something else (you can probably guess), but any automatic handgun in 9 mm, that is develop for service use would be ok with me. If ever it would have to be used it will be in VERY close quarter combat and caliber, stainless or not, night sights, etc. won't matter that much.
If I should address the 1911 A1 (maybe I shoulden't

) I have to say, our SIG 210 is except for the difference in caliber based on the exact same thecnics (still bad spelling, sorry). A SA only pistol is probably the stupidest thing to give a soldier (or policeofficer). I've seen my share of discharges because of this concept. Soldiers and policeofficers are not all gunnuts. A pistol that has a DA option for the first shot will be more safe
