Stock 2 failure to extract issue

No problem with my tanfoglio springs or many people’s I know.

it might have to do with batches.

 

I've suspected that there are batch related dimensional issues, maybe due to tooling wear & etc. 

 

That is just me speculating though.

I know first hand, Canadian distributor changes the extractor spring to wolf before shipping out and they do not sell tanfo springs

my stock 3 had this issue with s&b ammo. it ran fine on fiochhi, but once I switched to s&b it started choking.
I replaced the spring with wolff XP no mods to extractor or anything.
It mangled the brass a little, and was slower to feed in the beginning, but after some 500+ rounds it runs fine.

I had this problem. The fix is when placing the spring, have the last loop on the outside. Installed 2 this way and never had any problems with battery and extracting.

 

Not sure what that means, but I had one with a shallower spring pocket where the Wolff spring wouldn't go in, and I just clipped one coil off the spring and it's still happy 10k rounds later.
