Most gun people place the Sigs at or near the top of the list in nearly all categories.
I never recommend them because I've never owned one. Also, they are fairly expensive, and most new shooters are served just as well by any number of less expensive handguns that are going to shoot better than they are capable of, anyway.
But, I would say go ahead, if money is no object. If you are disappointed in a Sig, you would've been disappointed in almost anything else, as well.
