how good is Sig's SAO design?

[Ian's Dad]

looking for comments from folks with experience with the Sig SAO setup... thinking of adding one next in a P220 instead of another 1911...

do you like it? hate it? any input appreciated.

I have some Kimber and Colt 1911's and one lonely Sig X-5 TAC TB.

I love the SAO Sig, even though the TAC model comes with a non-adjustable 4.5# trigger pull. It's clean, crisp and great.
