Thank you William!
I think I talked to you about my issue on your website. I do have all the upgrades your company made for the 930/935 (including the follower), but I will definitely buy a new Wolff spring if you think that might help!
It seems to me that it either has to be the magazine spring that is the problem or the shell stop that is the problem.
The follower flows very freely down the mag tube and it seems pretty straight down the magazine bore as well. I did follow Nordic Components instructions of turning the spring ends into the center of the spring body, so I don't think that could be it.
