ok ready?you need to take the trigger, get in place with the tension on the spring, and place the disconnector in and get your trigger pin in to hold it in place. it will not be easy, any of this, so take your time. also if your parts kit came with a small vial of lube hit both pins. it may be easier to help you line these up by using a roll pin punch, i do, and it helps to keep everything aligned. next the hammer goes in, getting the tension on the spring and pushing into place, put hammer pin in and you're done. sounds easy. read this several times man then try. i promise you'll thank me if you have the punch's.
