I am not sure what Sig1911 the OP is intersted in and Sig have over 30 models listed on their website, and the price vary quite a bit. It was mentioned that the Sig was $200 more (with night sights) than the Ruger. Make sure it's actual night sights and not their high contrast sights which is not the same as night sights.
I bought a Sig 1911 TacPac for $900 Fall 2011, and I have been pretty happy with it. The chamber seems pretty tight and it didn't like lead ammo, but other than that it works well. It came in a nice hard case, two magazines, a holster/mag pouch combo, and a rail mounted laser. I think that was a pretty good deal for a Sig.
It's a series 80 gun, but bought a shim at Brownells for $4.95 that converted it to a Series 70 and now the trigger pull is 4#. It was the first time I had worked on a 1911 and it took my about 1 hour to do it.
Here is a link to a review of it.
