If one wants the best 1911 possible one is always better served by having a custom pistolsmith build him a gun to suit the specific customers needs. That way you get exactly what you want and exactly what you need. However, semi-custom shops like Ed Brown, Les Baer, and Wilson Combat often can give the user everything he needs at a moderate price and a minimal wait time. IMO production guns such as Kimbers, Colts, and Springfields (with the exception of the PRO Model) generally don’t come any where near to the products of semi-custom or custom makers.... no matter if it says “custom shop” on the slide or not.
With that said, if one wants the best 1911 produced today (without going to a custom pistolsmith) buy an Ed Brown. After that a Les Baer is a very close second followed by Wilson Combat. The Valtro is a pretty nice gun if you can get past the horribly ugly roll marks and the way too melted dehorn. With the exception of the Springfield Pro Model I don’t think any other major production house makes a 1911 that should even be considered if one is looking for the “best”, YMMV.
