One of the long established top quality barrel makers for 1911's is Scheumann Barrels.It is noteworthy that Kuhnhausen refers to them.

This link will take you to Schuemann's explanation of 1911 timing.

It has to do with the barrel being drwn down out of lockup by the link.This occurs till the underlug of the barrel contacts the frame,then the barrel stops moving to the rear,and it stops moving down.The slide continues to the rear.

It is critical at this point that the locking lugs are fully disengaged.

They must fully disengage during the dynamics of firing.

Almost,but not quite fully unlocking is harmfull to the lugs ,both barrel and slide.

The link gives a more complete explanation,and a description of checking it.
