It actually depends if you have or access to a drill press. If you take the trigger blade out you,ll notice , just behind the pivot hole, a small bar running across the top of the blade. This actuates the first stage travel and is, by it,s very nature, not adjustable. What you do is to mark a line on the side of the blade in line with that pin and parallel to the second stage screw. Then you cut the pin in half and pull it out. Then you drill a 2.5mm hole in line with your mark and tap it out with a 3mm tap. Then insert a 3x10mm grub screw and there you have it. It allows you to adjust the first stage and , consequently, the second stage to make a much lighter and more predictable let off. I got the idea from a guy on the Chinese forum and, I have to say, it totally transformed the trigger on my 208.
