I love all my 1911s. The CBOB is, to date, the most money I've put into any of them. To me, spending 2K on a 1911 just isn't something I want to do; there are other things that I would do with that money first. But I'm not disparaging anyone who wants to do so. I'd love to own a Wilson someday, actually.
The CBOB is just an incredible bargain, kind of like getting a Hyundai that has 90 per cent of features and quality of the same size Bimmer. I know it has a cast frame and that doesn't bother me. The new ones, btw, have Ed Brown safeties, iirc, in place of the STI mim part (which is an outstanding part, btw - mim in this area is not all that big a deal). They also use lots of other premium parts throughout, have great triggers from the factory, and tend to shoot pretty well. They're so tight that some people have had slides jam until they've gotten a few hundred rounds through them. If they were 2K guns, might they be a little better out of the box? Probably, but the shooter who's going to put a lot of rounds through it is going to "work out the kinks" anyway. DW also has outstanding service and stands behind their product. So, it's really personal preference and level of investment. I'm just amazed that DW has offerred such a great pistol at such a price.
