The single action trigger of the GP-6 is rumored to be nice though I can't see it getting anywhere near 1911-alike. That seems to be a point of the one informal review linked from STI's site.
If the thing warms the hearts of USPSA production division folks I could picture people not much caring what it looks like - if the Beretta UGB-25 is any indication, the one extra hit is worth all manner of non-traditional looks.
But, it's all rumor and speculation until the reviews start showing up. They seem to be moving briskly for Dawson.
