I have a Kimber 1911 that is fully tricked out for action pistol shooting, and for that purpose, I think it is just right.
I also have a Sig 220, and a 226. Both of these guns are far more reliable than any 1911 ever made. I talked to one of the well known gunsmiths who specializes in 1911's. He said that if his life depended on picking up either a Sig or a 1911, he would grab the Sig.
As far as accuracy, their is little to choose between the 220 and the 1911. Yes, the 1911's have the best trigger on any s.a. pistol, but the trigger on my 220 is quite good at a crisp 3 lbs. Still, it's your money, and you will make a great choice either way. But for defense it's the Sig. For IPSC, it's the 1911.
Your choice should be made based on what you want it to do.
