Hello all, I posted this topic in the armorer section the other day, but did not receive a response, so I figured I'd post it here. I detail stripped my P320 the other day and noticed an unusual spot on the inside of the FCU where the trigger is held in place by its detent. It's probably not an issue, but I was looking for a second opinion, and also was wondering if this is normal or something I should be concerned about. I'm most concerned about the spot worsening over time and leading to excess side to side trigger play. Any help is much appreciated! Pictures below:

Double posting is frowned upon here. You most likely received no response to your first post because no one can tell what they are looking at. The mere fact that you have to magnify the "spot" so much makes me think it is insignificant.

Welcome to SIGforum, by the way.
