Newer Glocks with tighter chambers a cause for weak extraction?

[Savage Hands]

I remember Todd mentioning how the newer Glocks shoot more precise than the older models, is it possible that Glock tightened the chamber up a tad too much? I'm sure there's a way to see if the chambers are on the lower end of SAAMI's specs.

A chamber within SAAMI spec should have no problems, period.

I do not believe chamber dimension changes (if any) are the cause of the improved accuracy seen with gen 4 guns.

Oh well, there must be another reason some of the 'fixed' Glocks are still having ejection/extraction problems.
