Guys I have been trying to install this Sig 365 straight trigger literally all night. I cannot seem to get the takedown lever bar to stay on the fcu when I do I can't push the down lever all the way. I have had to complete dissemble the pistol at least 4 or 5 times by now.. at this point I'm willing to pay someone. I spoke to a LGS and they said nobody works on them except Sig. I'm at the last point of putting it together if someone could help me out I would be greatly appreciate it! I will pay you for your time thanks!
