I own the Sig 1911 Stainless Steel Carry, 4.2" barrel. Can't say enough good about it. I have about 1000 rounds through it at this point and it has been totally trouble free.
Great fit & finish. Only thing I changed was the grips, put a Gadsden Flag set on.
A friend has 2 of them, a Scorpion 5" and a C3. Loves them both & they are both great shooters.
If I have to explain it, you probably won't understand it.
