I know this has been discussed here before but I was unable to find it through the search function.
Has anyone else had this problem?
How did you fix it?
What did Sig customer service do about it ?
Will the KNS non-rotating pin kit for an AR work in the MPX?
Thanks in advance.

I had this happen with my Geiselle trigger. They immediately fixed the issue with new pins. No need to get the anti walking pin kit, after they sent new pins.. Very fast turnaround.
If its the factory trigger, get Sig to fix it.

Well I talked to Sig customer service today, they want me to send the entire MPX back to them so they can assess the problem. He told me it would take three to four weeks to fix it. I really don't want my NFA engraved SBR out of my control.
