oh boy did i f-- things up this time. i just traded for a glock21 that had some upgrades done. one of the upgrades was a over-travel stop. well when i pulled the trigger, it didn't seem much different from the stock trigger on my G17. so what do i do? of course i take out the over-travel stop and tighten the screw more. i put the slide back on and now the trigger wont press. OK i will adjust it again....... cant take off the slide without pulling the trigger. WTF do i do now???
