If you are not talking about warranty work, the best way to perfect a Sig is to send it to Bruce Gray http://grayguns.com/. He is also a master shooter, on various factory teams. I've had my pistol to him for trigger work and so forth and he is excellent, so excellent that his lead times are starting to get a bit long, but if that isn't an obstacle, I recommend him very highly.
