I have been considering the same. Though to fill that void I recently purchased a MP 45 Shield to placate the "bigger" handgun void for now with the probable intentions for going to a 10 round 45 later on. The Shield will be my primary carry piece for now. Sig makes a good gun but I think the S&W is the way to go. If you can find a range that will allow you to test fire one is the best way to determine it IMO.
