I agree somewhat with what HOLYROLLER said. "Someone's name on the side or another 1911 for your opposite hand". I'll add "Bragging' Rights".
I do not have any "expensive" handguns. I have only bought guns for self defense, so far. I have no interest in tight groups at 25 or 50 yards. My HK's can stay on a 8.5" x 11" sheet of paper at self defense distances, drawn from a holster and quick sight acquisition, so that is all I need.
Even what some have said about slower follow-up shots do not matter in self-defense. If your first shot is at center-mass, and your second shot is a bit higher, it will still be on the bad guy.
I guess you have to decide what your purpose is with the gun. Self Defense, IDPA, USPSA, Bullseye, etc.
The only 1911 style pistol I have is a Para Ordnance P14-45 LDA, which I call "1911 Style", because some 1911 purists poo-poo it as not being a "real" 1911 because its DA trigger. I don't care - I like it. The trigger is closer to what I am accustomed to shooting: All the rest of my guns are HK's and 1 Glock.
There is a Bullseye Pistol Team at my local Sportsman's Club. Many, if not all use 1911 for the .45 caliber portion of the Bullseye Matches. They range from out-of-the-box stock 1911 to $5000.00 customized 1911. One guy told me he took a Springfield Mil-Spec, which is what he trained with in the U.S. Army, and had his gunsmith customize it. When finished, it cost about $5000.00 total. Then he bought another Springfield Mil-Spec and had the exact same work done on it, so he has a spare, in case of malfunctions. That is, in case you can't add, $10K to compete in a hobby, with no cash prizes! He says if he waits too long before cleaning, the guns start having problems, since the tolerances are so tight. These guys shoot at 50 yards one handed, most with open sights!
The question remains: What do you want the gun for?
I would recommend that you take the Mil-Spec and just have a little gunsmith work done on it.
If you want near-absolute reliability, stick with your USP.
Also, try wearing gloves when you shoot, and your hand won't get beat up, or even try a Band-Aid on the spot that gets beat up.
