The wife has one about a year old. She'd only put about 300 rounds through it when it stopped functioning. Dead trigger. Sometimes racking the slide would reset it. Sometimes it wouldn't. Sent it off to Sig. They paid for shipping. Came back in exactly 8 days. It works now.
Sig said the sear pin was out of place. In addition they upgraded the magazine catch and the mainspring housing and replaced the grips. We never noticed an issue with the grips, but they said they were damaged. Was not happy that a $750 gun less than a year old quit working, but I'm VERY pleased with Sig Sauer's customer service.
It's a real nice pistol, but IMO a single action only pistol should not have a 10 pound plus trigger pull. That's just wrong.
