I love it when someone says, "should I get A, B, or C?" and people say "D" with no reason as to why. Why should the OP go with a Sig or an EMP over his options?
Ok, I'll follow-on to my previous EMP agreement...
1) Springfield's warantee program is exceptional. I've never had a problem with either of my EMPs, but an older 1911A1 was fixed on their dime, including shipping, even though I wasn't the original owner and it was over ten years old at the time.
2) EMP points naturally, like all 1911's, due to the grip angle.
3) EMP is machined to very high tolerances, almost everything is match grade or close enough.
4) EMP is very accurate for a 3" barrel - even if I'm the one shooting it.
5) In over 10K rounds from two, I have never had a misfeed that wasn't my fault.
6) In the same 10K rounds, neither shows significant wear or any rough surfaces.
7) EMP is short, narrow, and low enough for easy concealment.
8) EMP is all metal, yet not appreciably heavier than any of the other options.
9) Not too relevant, but it's prettier than any of the others.
