Call SIG's customer service. While I had no malfuncions, I was concerned about the DAK trigger on my P229 SAS. I pointed out my concern and they immediately said they would e-mail a prepaid overnight shipping label to me and check it out. 7 days later it was back after having the trigger checked out and brought into tolerances.
Excellent customer service--call them now. Phone: (603) 772-2302 (press #3 for Customer Service).
