Well, the 7lb trigger will teach ya good trigger finger discipline.
I installed the pre-B disco last night. I needed to fit it for my S2. The ears on the disco weren't clearing the trigger bar allowing the trigger to fall forward when the sear was disengaged. Trigger reset is a bit shorter than the S2 factory disco. Took me close to 4hrs to fit... The first 90mins of that was me on all fours looking for the damn sear pin that fell off my workbench. I just about gave up when I just happened to see it, well away from where I saw it fall. On the plus side, the floor and mats are nice and clean now. I have no idea how it ended up halfway across the room. Then 30mins of me trying to figure out why the slide would not cycle as soon as I inserted the slide lock, only to eventually realize that I was inserting my Tanfoglio's slide lock instead of my S2 one. FFS!
