Rival slide wear

Hi guys just realized this ‘might’ be an issue but just wanted to see if anyone has same experience. I am a uspsa shooter which this is my CO division gun everything stock only changed trigger shoe. 1, is this gonna be a problem eventually? 2, what case this? I don’t see any contact point from lower frame

This is a great pistol only fail to feed once from i have it. Overall round count is 7K ish. Ammo i use is 115 gr generally fiocci federal and monarch all brass but I don’t think this related to ammonia use.

Thanks
