short hopefully simple question.

 

 if i'm gonna install a micro-comp on a glock, do i need a crush washer? 

What does the manufacturer’s install guide say?

I have never heard of that, but I haven’t used every comp ever made:

Almost certainly not required.

I don't think I have ever seen a pistol barrel thick enough that there is a step behind the threaded portion high enough to crush a washer against.

How would you "time" it w/o one?

i found a video after i posted this. it's a tbrci. they show it being done with the slide removed, and the guide rod/spring removed....laid on its side to line it up properly(i'm guessing that's what's being referred to by timing it?), then using the 2 set screws on the sides to lock it down. they say to torque it to 12 lb ft.

PMM comps use shims:
