mo, My Scott Little Goose, does exactly what you describe, if I'm reading your post correctly.

I have the set-screw set where it's like a hair trigger. So far, I have never had it open up during the draw cycle, but I also keep my index finger firmly pressed behind the trigger while I'm drawing. Again, the set-screw is set where the trigger pulll is very light. Another thing, when I first bought the release and wasadjusting the set-screw I noticed that it (the screw)seemed kinda loose, so I put a little tiny strip of teflon tape on the threads to tighten it up. I've haven't had to adjust it since. It's been at least4 years maybe 5.
