As a 1911 aficionado, that's what I carry. Most of my 1911s will feed pretty much any JHP round, but for consistent reliability I prefer those with a rounded ogive that's close to the ogive profile of FMJ bullets. In premium ammunition, that basically means Remington Golden Saber -- except that Remington has now renamed it "Personal Defense" (or something like that) and raised the price in a shadow increase by keeping the price per box the same, but now packaging 20 rounds per box instead of 25.
Some while back I did a fair amount of research into self-defense loads in .45 ACP. Both Winchester and Remington offer (or did at that time) a JHP load in their budget ammo lines (Winchester "white box" and Remington 'green box"). The bullets in those rounds look virtually identical, and they also appear to be the same bullets you get if you buy 230-grain JHP projectiles from either Winchester or Remington. What I found strongly suggested that these bullets were originally the premium JHP from the respective companies, and they relegated them to the bulk pack lines when they introduced newer, higher-priced self-defense loads with fancy names (like "Black Talon") and commensurately higher prices.
I found some tests that indicated that under most conditions the budget JHPs expand almost as well as the newer, higher-priced ammo. I still have a few boxes of Remington Golden Saber, so that's what I carry in my EDC pistol but I would not feel under-armed if I were to load up with Winchester white box or Remington green box JHP. A gunsmith friend of mine takes the attitude that if it doesn't expand at all, it still makes a .45" hole, so it's no worse than ball ammo, and probably significantly better.
