Let me preface this with a reminder that I'm not a gunsmith-just a fellow who'd built a few guns and worked on them for personal use:
What you're seeing is the thumb safety not engaging completely, and allowing the sear to move out of engagement with the hammer slightly. Without knowing the sear geometry and other details, you have no real way of knowing how close the hammer is to being released. Also, a very
hard pull on the trigger will likely move the sear more.
Essentially, you're no longer certain the safety is working-'working' means working completely correctly, IMHO
-and I wouldn't carry the gun depending on such a safety to keep holes out of me or those around me.
