My recent dalliances with full size 9mm 1911s got me started looking at something to replace my .45 Commander that's going to one of the boys soon. I ran across an EMP listed on a forum so I started doing some searches here and was reminded about the 4" model. Curiosity got the better of me and I went to the Springfield website to do a comparison. Unless I'm missing something subtle in the details or dimensions, it looks like the only differences are a half oz of weight (EMP 31oz vs Champion 31.5oz), the EMP having a stainless slide vs carbon steel and the EMP comes with 3-10rd mags vs 2-9rd for the Champion.
Is there something about the EMP that's thinner or some other felt difference that's not listed? Given that it uses proprietary parts and AFAIK the Champion uses "regular" 1911 parts (besides being set up for a bushing-less barrel), I'm not sure I see the appeal for the higher price. At least with the Carry Contour EMP I can see something different from the Champion.
What am I overlooking?
