I think the cure is a stronger spring.
Had the same issue with my Manticore 32 round mag and it was worse after adding a Taylor Freelance +10 extension and using their spring.
Emailed Taylor and now am running a modified Glock 32 round magazine spring.
OMG, the follower pressure is perfect now. Feels just like a factory 20 or 30 round mag.
42 rounds is pretty cool too
