It should have been a 1911, made in America by Colt. It should not be from a company from a country that was responsible for a lot of those headstones being there.
Sig does have a plant in the US so the idea that the guns are made elsewhere doesn't fly. In these days of terrorism, the selection makes a lot of sense.
That they only made 4 kinda raises a question though. It would appear from the picture that only the tomb guard not walking post is going to have the handgun. Wonder if that indicates that the magazines on the rifles are loaded?
Let's add some perspective here.
Back when I wore the uniform, my girlfriend's dad was shopping for a car, and I went with them. Some of the dealers sold both foreign and domestic brands, and the third time one of the salesman tried to steer him to a Japanese car, he button holed him and said in very clear and uncertain terms "I didn't spend three years in the Pacific to buy a Japanese car." This mild mannered dry cleaner had never mentioned it before, but he was in fact a fellow Marine and nearly 40 years after his service in the Pacific at Guadalcanal, Tarawa, Saipan and Tinian, it was still a deep seated issue for him, regardless of our relationship with the post imperial Japan.
There's also my uncle Gale, who lost most of his platoon crossing the Rhine under fire. He would in no way shape or form ever buy a German car, and no one who knew him was dumb enough to suggest it.
That generation has almost died off. But my view is that this "honor" by Sig Sauer spits on their memory and on the memory of a significant number of soldiers buried at Arlington. The "Sig" part of "Sig Sauer GmbH" is Swiss, and we've never been at war with them. However, the "Sauer" part of the 1976 merger that resulted in Sig Sauer GmbH came from the JP Sauer and Sohn company, which has been producing firearms in Germany since 1751.
In addition to all the firearms and firearm parts they made under contract in WWI and WWII, the company's Sauer 38H was adopted as a German alternate standard pistol as Modell 38 and was widely used by Luftwaffe and Panzer forces.
I suspect many WWII vets, alive or dead, who lost comrades in Europe or in North Africa would not regard a Sig Sauer P320 as a much more appropriate choice than the Sauer Modell 38.
Sig Sauer's efforts to gussy it up with all the symbolism doesn't change the fact that Sauer made the weapons, or parts of weapons that were responsible for a lot of the US casualties that occurred in WWII.
-----
That issue of basic respect for our honored dead is entirely separate from the issue of whether the Sig P320 is made in the US or not, and whether there is any meaningful organizational separation between Sig Sauer Inc. and Sig Sauer GmbH.
The US company is Sig Sauer Inc, which became the successor to SIGARMS about 10 years ago. SIGARMS started importing Sig Sauer GmbH weapons into the US in the mid 1980s.
Interestingly if you look at the press releases regarding the P320 US military contract you will see references to "Sig Sauer USA" winning the contract. There is no such company and it's an effort to downplay the Swiss and German underpinnings of the company.
I have no doubt that the pistols will be required to be manufactured in the US, to whatever criteria for US manufacture was defined in the contract, but it's still not the same as the pistols being made by a truly American company.
And, it's certainly not the same as having our honor guards at the Tomb of the Unknown Soldier carrying a Colt pistol. All the phony symbolism engraved on the pistol won't change that fact.
I'd much rather see them carrying US made and issued 1911's, reworked by US armorers to suitable presentation status.
