That is correct, Tex,- a weak spring causes all sorts of problems.

Wolf offers "extra 10% power" round springs and new zig-zag springs for the later mags.

GT also has springs, and when he works on/ re-works a mag it most of the time gets a new spring.

A really weak spring won't raise a cartridge fast enough to chamber, nor will it operate the hold open.
