I've been dealing with this issue for a couple years now. I had some work done on my model 57 a few years back. I thought maybe the issue might wear in and fix itself. After the gunsmith returned it, I noticed that there was no over travel in the trigger. When pulling the trigger, it feels like the trigger is pushing against a stop before it breaks. I would really like just the slightest amount of over travel when pulling the trigger, so it doesn't feel like it is bottomed out. I suppose I should have brought it back to the gunsmith, but it is a 45 mile drive, and as I stated, I thought maybe it would smooth out. There is no pin inside the trigger return spring, so I don't know if there was one originally, or not. Anyway, my question. What can I do to allow a tiny but of over travel in my trigger pull?
