Does this movement take place when you are pushing down on the top of the barrel hood with the barrel and slide in lockup? If it is, then it is the barrel fit in the slide and on the slide stop pin. Specifically, it is the curve of the lower lugs causing the movement, this is because the upper and lower lugs have too much clearance...common on a mil spec barrel assembly.

It seems the slide comes back about 5 thousandths before the barrel comes unlocked. Do you think I have the wrong link in there? There is no push down on the hood. I have between 0.48 and 0.50 lock up.
Thanks
