Before we go any further- this mod will most likely void the warranty on the frame and possibly the gun. If you don't know what you're doing, please do not attempt to duplicate.
What's that set screw doing there? Yep, I drilled and tapped the frame for a 1/4"-20TPI set screw to be used as a trigger pre-travel adjuster. This takes up all the pre-travel the trigger would normally do before actually striking the firing valve.
It's roughly a 3mm pull, tried it out via dryfiring and I'm not getting any shortstrokes or chuffing or anything, so I'll call it a win. I can actually go a little shorter, but I prefer it how it is now. Also- much to my surprise, the safety still functions!
