I havent carried a 1911 for over 20 years now. When I did, I carried 230 grain Hydra Shoks in them, as they were supposedly the round to beat at the time and they always fed like ball in all my guns. Those guns all had had a reliability package done to them too, so they would feed most anything.
Personally, as long as the gun feeds them well, I would choose a 200 grain lead, or plated/jacketed SWC, over ball. I think with that sharp shoulder, youll just get better performance out of them. Never had any issues with reliability in my guns either.
As far as war stories go, always take them with a bucket full of salt and a squinty hairy eye ball.
My dad was a three combat tour VN vet, along with a few other garden spots, who retired (was actually pushed out at 30) from the Marine Corps as a SGTMAJ. I heard a lot of "stories" growing up, from him and others. The difference between BS and not, is usually pretty easy to figure out, just by whats being said, whos there when they are told, and the look on their faces as they tell them.
The old man carried a 1911 most of his life work or not. As far as I ever heard, they carried what they were issued in their work guns, and out of work, over the years as time and things moved on and improved, he moved along with it with his personal stuff, both guns and ammo. Last I saw before he died, he was using Hydra Shoks too.
