1/8 of an inch back is just about where the barrel should be starting to unlock from the slide. My first guess is that the fitting of the barrel to slide is slightly off and the barrel (top) lugs are hanging up on the slide lugs.

Slather the barrel lugs up with light grease or heavy oil and see it the problem goes away, or becomes less severe.

You may also have too long a barrel link installed. Have you run Scheumann's barrel timing test?
