When did you move to Utah? I'm sure you can find a gunsmith there. If your problem is with a new Sig and it's under warranty, ask Sig where to send it.
I bought a new Sig P250F. I was totally disappointed with the DAO trigger. Sold it. I have recommendations to other Sig models but haven't decided to buy any yet.
Married 28 years---I'm starting to think it might work out.
