I look forward to seeing the movie. Both Cruise and Pitt are fine actors whether one agrees with their off stage antics or not. And since all actors are narcissistic to some degree I take anything they say or do while out of character with a grain of salt.
In "With The Old Breed: st Peleliu and Okinawa" Eugene Sledge writes about a 45 that his father sent him for personal use. In the HBO miniseries it it shown several times and appears to be a commercial S&W 1917 type with checkered stocks. But I don't recall reading in the book whether it was a revolver or 1911.
My own father served as a Naval aviator in the North Atlantic. In addition to a Victory revolver, he carried a rather large hunting style knife that my grandfather made out of a broken file. Grandpa worked for the NYC RR and got the file from the Avis, Pa, engine shops. He made the sheath too, out of some old machine drive belt leather. Still have both though the sheath is a little worse for wear.

Can you picture the knife? Sounds interesting. I think Naval aviators were usually issued MK 1 knives or bought their own.
If you watch, "The Bridges at Toko-Ri", William Holden's character was wearing what I think was a Western brand "shark knife." He was a lawyer from Denver and Western was in Colorado, so that was very plausible. I saw their knives in most suitable stores while I was stationed in Denver in the 1960's. But I bought Buck and Randall. I did get a used small Western sheath knife, which I still have. The movie, of course, is about the Korean war, not WW II. You can sometimes find it or excerpts on YouTube. Good film!
BTW, in the book, I think James Michener (sp?) mentioned that the pilot hero had fired his Victory Model .38 just six times in training. That seems very likely. When his F-9F Panther (a Banshee in the book) was shot down, he reflected about that. I won't say how he got a .30 carbine or how it ended; that'd be a spoiler for those who haven't seen it. The movie also starred Mickey Rooney and Grace Kelly.
I was in the USAF but sometimes saw Naval aviators. They had Victory Models and knives were evidently up to the man wearing it. I saw only a couple of Randalls; most were less expensive.
For the Vietnam war, I like the book series by a pilot who flew Intruders. "Flight of the Intruder" was his first book. His name momentarily escapes me, but you can find the book by title. He mentioned that on the carrier, pilots had a small locker in their rooms to store a sidearm. I think he wore a S&W M-19 .357, like his hero, Jake Grafton. His pal had a Colt M-1911A-1 and a big knife similar to a Cold Steel Trailmaster, but not one of those.
Back in the Viet years, it wasn't uncommon to see milltary pilots asking gun magazine columnists about sidearms. Some AF bases told pilots to bring their own, as there were shortages. Naturally, Jeff Cooper advised buying a Colt .45 auto...

But it was a sound choice, at that. Jeff could be more versatile. He liked the M-19 with six-inch bbl. as a trail gun, making the point that it had a lot of power with less bulk than most .357's. And it shot flatter and was more useful in the wilderness than a .45 auto, with .38 ammo for small game.
