Combined Freddy Z's mag with a cut-up Sure T Mag spring and replaced Freddy Z's follower with the Sure T Mag one as it had better tolerances. The cut-up spring works just like a whole one and can fit on the plate easier.
Freddy Z's mag is fantastic as it prints lengthwise so the follower action is smoother. Also, the bottom allows easy disassembly of the mag.
