there is a safety engagement adjustment screw that you might need to futz with.
These triggers are quite easy to modify, there are basically 4 screws. 2 adjust the limits of the trigger travel - creep & overtravel. Then there's the safety adjust. And the spring tension screw which is self-explanitory.
Take the entire trigger apart, and toss it in your brass tumbler overnight for a nice shiny polish on the moving bits. Tweak the travel screws for an extremely short trigger pull with no creep or overtravel. Then adjust the safety so that it works, and loctite all screws. Lastly, adjust the tension as low as you can without getting slamfires, and work the bolt & dry fire a couple hundred times to make sure everything is all good. It takes an hour's effort to get these things down to around 3lbs - which is as light as you can really go with this design. A good smith might be able to get a bit more by stoning the engaging faces, or altering angles - and glassy-smooth.
