I bought and installed the SteveNC Supersear a while back. It works well, but it always bothered me that the 1st stage would not return. I came up with an idea to fix that:
It works very well, and makes me happy. You just need a small tension spring, drill a hole in the swell of the trigger and file away a litte of the brace to the bottom screw post. Only took a few minutes and did not add too much to the trigger pull. This along with a thin shim at the trigger post makes for a really nice trigger!
