I'm a hinge trigger fan. This is not just a redo of 10 year old tech. Significant changes were made to create what I think is the best trigger on the market. Single stage or two stage capable. I can go from 1.3# to 3# trigger pull without changing sear spring tension. Developed for accuracy sports but I also run them in my Limited gun and L10 1911. I can tune the feel and break to any preference, amazingly accurate feel.
Since the hinge is not allowed in SS division, there is another alternative. A two piece trigger that allows for more adjustment than regular slide triggers. Change the shape or length of pull (or both) as the bow has a threaded shaft that the trigger shoe screws onto. The bow is not too long, like I have found with other triggers. Mine dropped straight into my Springfield frame with no more play than the trigger I pulled out (STI blank). I prefer a reverse curve trigger and Christoph nailed it! Both styles available for both 1911 and 2011's. I'm not a dealer, just a fan of them.
