"What is your dream 1911?"
Because there are endless variations on the 1911, both from the factories and from custom pistolsmiths, there really isn't one answer. It is different for every individual.
For instance, I objectively know that a SA Professional is a really cool gun. But I've got zero interest in having one. I've got no use for 20 LPI checkering, or magwells, or Novak sights, or polymer finishes, or... you get the idea. I don't care how nice it is; it just isn't my thing.
My dream 1911 is being put together by Ted Yost. It is EXACTY what I want. Those wants may not make much sense to anybody else, however. That's the beauty of custom guns, you aren't stuck with what other people think you should have. Is that the right way to go for everybody? No. Some people will be content with an off-the-shelf solution. Some people will want custom guns that are completely different from what I'm getting. If that gets you what you want, who cares?
Although, I have to admit that I feel a bit like Doctor Frankenstien as he's giving the monster an extra jolt of voltage to get it started. My old custom Delta pretty much fit into the mold of what everyone expects to see on custom guns; the only real novelty was that it was a Delta Elite. The one Ted has... well, it is going to be really different. Mua-hahahahahaha!
