I too have this problem after owning it 3 days. I put 225 rounds trough mine Saturday and Sunday(today). And mine looks like yours. In the next day or so, I will also post a topic of my own about a trigger problem I am experiencing.
Throughout the 225 rounds I sent down pipe the trigger would sometimes remain stuck back just for a second then it would click back. During the first 40 it would stick and sometimes I would have to tap it slightly to get it to release. After that it would free itself about 1 second after I would release the trigger. It did not happen during every magazine but it happened with both magazines. Probably about 20 or so times. Any body else have experienced this with this gun or any other safety trigger gun? On the good side I thought that the SR9C was a very accurate conceal carry piece and a good shooter. I will probably be sending it to get the trigger looked at.
One last thing, I noticed on mine when doing the initial degreasing and cleaning that the bottom of the trigger guard was dull. Looked to me that they missed polishing that one spot. Any others have this?
