Commander Size Under $1,000
Lots to choose from. Its always fun picking out a new 1911. You have indicated that you would like to stay below $1,000, 9mm, and no rail. You will likely have a lot of suggestions to go with the Colt Commander, either in the Combat all steel or Lightweight with aluminum frame models. Those will be of course great suggestions and I can't knock choosing one. I like them a lot. But, there are other worthy picks, too, that I have found "shoot fine and last a long time".
Colt Lightweight or Combat Commander - I found the Combat Commander for $860 and Lightweight Commander for $928 online. Availability can be an issue. My own is a recent production model lightweight. I like having the Colt name, but really don't see that it performs any better than a lot of others. Of course, I've been told that they will "hold their value". Really not much of an issue with me as I don't plan on getting rid of any of my Colt 1911s, my heirs can decide what to do with them.
Remington Carry Commander - Available online for about $750. Can often be found on sale for less.) I have had good luck with Remington 1911s that were made in Ilion, NY. The Carry Commander is dehorned and I think a very attractive pistol. Does have series 80 style safety. Does not use the double spring configuration that some manufactures have went to, which for me is a plus. YMMV.
Ruger Lwt Commander 9mm - Can be a little hard to find. Should be about $750 online. Ruger decided to approach the product liability issue with firing pin block safeties differently and have used a titanium firing pin and have not included the series 80 firing pin block safety, so can be called Series 70 type. The Ruger 1911s I have owned have shot well and have had very good triggers right out of the box. The two tone look that Ruger produces can be a plus or minus, depending upon your tastes. The dark color is matte. I don't have a Ruger Lwt Commander currently, but do have the 5" Lwt.
Kimber Pro Carry II 9mm - Current price I found online was $726 for the one I show in the picture, two tone with wood grips. Lots of Kimber haters around, but they have been good pistols for me. The Kimber Pro Carry models have barrels 1/4" shorter than a true Commander length, which as made originally by Colt should be 4 1/4". My Pro Carry is in .45 ACP and is my preferred Commander for EDC if I'm carrying a Commander.
Dan Wesson Vigil Commander - I hesitated to list this one as an option. Most prices that I found were slightly above your upper limit of $1,000. They currently have a MSRP of $1298. I have seen these for $915 - $950 from one dealer online. Dan Wesson has a very good reputation for making 1911s and the Commander Vigil should be one heck of a pistol. It is on my wish list, along with a Valkyrie, which has a Commander slide on a CCO frame.
