At the risk of taking it to a bit more well-defined level, "caliber" simply means it's bore diameter in inches. In this case, if you say ".45 caliber" everyone knows you are most often going to be referring to a ".45 Auto" or ".45 ACP", but calling it a .45 caliber could lead the more creative among us to consider that it's a .45 Colt, .45 Schofield, .45 AutoRim, .45 WinMag, .45-70 Govt, and god only knows how many others.
In fact, what you are referring to is more clearly defined as a chambering, though most people don't care either way. It's not a big deal like calling your magazines "clips" which bothers a LOT of people!
If you strive to one day own a 1911 in .45 Auto, I wouldn't make it a priority to buy the finest, best, most expensive one out there. You could get knocked clean off your chair by some of the prices. But do be prepared to spend between $700 and $1,500 to get yourself a very nice, very high quality 1911, and once you've become infinitely familiar with it, then start thinking about how to spend $2500 and up on one single "ultimate" 1911 pistol.
Also, here's a tip with TFL forums.
Do you know what would happen if you walked in to a stamp collecting convention with 2,000 people, you got on stage and said, "I don't have any stamps. I want to buy some nice, historic, collectible stamps. What do you people think?"
Imagine the answer you'd get from 2,000 stamp collectors in attendance.
That's kind of what you are asking if you come to TFL forums and say, "I like a 1911, which one should I buy?!"
