A good job deserves being mentioned- more often than not, all you hear is the bad.
I recently bought a Sig 365 manual safety. I noticed, days after receiving it, a small area of finish missing on the slide, where the left side safety lever was hitting. I belong to Sigtalk, and I (later) happened on a post, about the same issue. The poster included a photo, showing that the safety lever was asymmetrical in the slide- there was liberal space between the right side slide lever and the slide, while the left side would rub. Mine was the same. Reading further, other owners had the same condition, and Sig was fixing them. So, I contacted Sig and got an RMA.
I dropped the gun off at a FedEx depot this past Monday, the 9th. I was expecting a notification email that they had received the gun. I found an email from Sig this morning (the 12th), and was very surprised to find that it was a notice of return shipping. The 365 has been repaired (no information other than it's finished), and it will be delivered tomorrow. 5 days turnaround- that is exceptional.
I definitely had not expected such quick service.
