Which 1911?

I have the most confidence in the Kimber, the TLE II is a great pistol, and the latest ones have the internal extractor unlike the Sig

Colts are awesome and dont have as many flawed designs as Kimber.

I'd chose a Springfield custom over any of those though.
No offence to Kimber, Colt or Sig.

I don't care for the grip safety on the Colt XSE models. It is typically referred to as the "duckbill". The standard blue Colt Commander #04691 has a much better grip safety in my opinion. The XSE models also have the ambidextrous thumb safety that I don't have a need for since I'm a righty. While the #04691 also only has the strong side thumb safety and in my preferred "teardrop" design.

Sig's have a slightly different slide profile that may not fit in a typical holster designed for a 1911 unless specifically designed for a Sig 1911. Sig's also have an external extractor. You may or may not like either of these departures from the traditional 1911 design, just know they are different.

Kimber has the Swartz style firing pin safety while Colt and Sig use the Colt style Series 80 firing pin safety. Both designs will most likely work just fine. Once again, just know what you are getting and decide if that is what you want. The TLE Pro II also is a 4" pistol vs the traditional Commander length 4 1/4" Colt (I'm assuming the Sig is the 5" model?). The Kimber will have a bull barrel and full length guide rod (requiring a tool/paper clip) to disassemble while the Colt will have the barrel bushing and short guide rod and will be able to disassemble without tools.

My Kimber's serving me pretty well, and I hear of issues with the SIG-style extractor every so often. All of the post-WWII Colts I've seen struck me as being slopped together rather poorly for the money they command......I guess that, as someone who doesn't drink any cool-aid, that I have trouble seeing where the money is in sticking with the pony.

Kimber's CS is pretty much top-notch as well.
