From the FAQ thread: "Gen 1 had a decent trigger, Gen 2 had an good trigger but some minor problems (extractor), and Gen 3 is rock solid - best trigger, and dependable functionality." I really want to fix the rough take-up and mushy reset on my Gen. 1 S9, and at present I'm gathering all the info I need so it's not just wading in with Brute Force and Ignorance. Are there Gen. 3 parts that can be swapped to smooth things out? I plan to get BT's guide rod & delrin bushings, maybe striker spring. Does the presence of the manual safety complicate things? I would like to reduce the amt of force req'd to disengage it, since I can't push up hard enough to work it. I don't wish to remove it. What part(s) should I order just in case? It's my EDC piece so having it down is not acceptable. Should I replace the extractor? It has never failed to extract and "If it ain't broke, don't fix it" comes to mind. Thanks for any help.
