Installed late last night and everything went very well (except one little thing I'll talk about at the end).
HOLY REDUCED TRAVEL BATMAN!
That's going to take some getting used to.
In dry fire practice it's crisp, concise and smoooooth. Me likey.
Now for those of you installing yourself there's something in the video I'd like to expand upon for ease of disassembly and reassembly.
At about 5:57 he takes out the Take Down Lever.
After you get it most of the way out it feels like it's stuck and he says "Turn it upside down and wiggle it back and forth. It will come out."
What's keeping the Take Down Lever in there is the Slide Stop Spring. Right after he pulls the Take Down Lever out he shows the end of the Lever: there's a nub.
That nub is important for reassembly!
At 8:35 he again shows that nub. What you're doing is using that nub (by rotating the Lever) to push the Slide Stop Spring down to allow the Take Down Lever to pass. So like he did, start with the nub on top, and simultaneously rotate the lever clockwise while pushing it in. You can view exactly what you're doing if you look down into the Locking Block while doing it.
Understanding that little part will ease reassembly and keep you from mangling your spring like I did!
***My Slide Stop Spring hasn't been damaged beyond use but it looks like it's been chewed on.***
