No, not the TRS.  I got that in.  I am having an issue where the trigger bar is slipping out of place off the plunger when I place in the hammer and hammer axle.  It then binds everything up and I can't put in the sear.  What the F?

Honestly, this video is the best I've seen, and I have it downloaded on an iPad when I'm breaking down/reassembling my USP (which I've done too many times to this level). The only thing I can think of is maybe the plunger spring is kinked so the plunger isn't exactly straight under the bar, or the hammer axle is rotated somehow so it's not capturing it right. The trigger bar stuff starts at about 4:30.
It takes away some of the visual impact when you can't see it.

Yes, MosinVirus was a great channel.  That video is great.  I fixed it today.  If you don't let the trigger bar back up into the notch in the "axle" it allows to bar to slide off the plunger and muck things up.  If it gets captured in the axle slot, the gun goes back together fairly easily.  Lived and Learned.

Came to post this very video. Best disassembly/assembly videos I've come across.
