You should get an S&W Model 629 with the 5" barrel. No, wait...that's what I want to get. That's the problem with asking on the internet; everyone injects their own biases into the argument. The only advantage is you might hear a few pro/con suggestions that you hadn't thought of.
Personally, I find the EMP to be a slick, cool little pistol, but I am put off by the price. You'd think that Springfield would have made it a little more production-friendly (ie. cheaper) when they massaged the 1911 design, or maybe they're just milking the 1911 wave for all it's worth.
Either way, I'd get the Stag first, and see what happens with the EMP down the road.
