I installed a M2.5x 8mm screw in my Gamo Swarm Whisper to see how things would go. It did lighten the trigger pull some, but overall travel remained the same, it seems. In that gun with the longer screw, it feels like there's more 'dead space'/first stage travel with a shortened second stage/quick break with the longer screw installed. Honestly, my fingers aren't the best, and I find most triggers ok as long as the claimed pull weight is 4#'s or less. My favorite trigger is the T-06 (Diana), but everyone has their preferences.
