I've have or have had 1911s from Kimber, Colt, Springfield, Les Baer, and Wilson Combat.
My Wilson Combat CQB Compact is head and shoulders above the rest with my Les Baer Thunder Ranch Special being a close second. These, however are rather high end custom guns.
As far as production 1911s go, I've been nothing but happy with the various Springfield Armory specimens that I have and have had. I presently have a Springfield TRP which is my primary carry, however, it's very close to losing that title to the Wilson. I also have Springfield EMP 9mm that is my primary carry during the warm weather months. It's small, lightweight, easy to conceal, accurate, and VERY reliable. I also had a Springfield Armory Loaded Target that I parted with in favor of the Les Baer TRS. The Loaded Target was an outstanding gun as well and I had no problems with it.
The Les Baer, while an outstanding, reliable and accurate gun, is fitted almost unreasonably tightly...so tightly in fact that even having 1,500 rounds through it (it's still in its infancy), it's still difficult to rack the slide with a standard 16 lb recoil spring without first cocking the hammer. The barrel bushing is also incredibly tight. The tight fit of the gun has not adversely affected reliability thus far, but I'd still like to see the gun wear in a little more before it gets any belt time.
Of my Colt, it's an XS CCO and it has been 100% for me as well. I simply don't like that it doesn't have night sights, and that it's not particularly well suited to many of the various night sights out there without the rear dovetail being substantially modified. It's also not beveled off on the edges as well as my other 1911s.
On the Kimber front, I've had three and still have two. My three Kimbers were an Eclipse Custom II, a Custom Royal II and a Desert Warrior. I still have the two former and the latter was let go even though it was the most functionally reliable.
The Desert Warrior was 100% with hard ball ammo, but slightly selective of JHP loadings, it was also much more loosely fitted than either of my other two Kimbers. Accuracy was there, but I really did not care for the very slick Kim-Pro II finish coupled with the fairly aggressive melt treatment. The slide was difficult to rack with cold, or wet (i.e. sweaty) hands, and the grip wasn't the most positive due to the slippery finish and the lack of front strap checkering. What I liked about the gun was that it had an excellent trigger for a production level gun and it lacked the Series II Swartz safety system found on my other two Kimbers.
Both the Eclipse and Royal are decent guns, but I'm not sure that they were worth the price I paid for each respectively. I don't particularly care for the Series II Swartz safety and had issues with it on my Royal II requiring a trip back to Kimber. Apparently the push rod that disengages the firing pin block was slightly out of timing and wouldn't properly disengage the firing pin block every once in a great while (three out of 100 rounds approximately). The system on that gun now works, but I don't trust the gun for carry purposes because of this prior issue.
The Eclipse has been a bucket full o headaches from day one. The chamber had to be reamed out as it was too tight from the factory, the gun is highly ammunition selective and the same way with magazines. The long and short of it is I really want to likle this gun because it has great potential and I love the striking appearance, but thus far it's just not delivered.
The long and short of this rather lengthy post is your best bet in the $1,100 price range would be a Colt or Springfield. With a substantially higher budget, Wilson is the way to go. The gun is fitted tightly, but not overly tight as I feel the Baer is, the accuracy is far better than I can capitalize on, and the gun's dimensions are perfect for SD use.
YMMV.
