9 m.m.?
Metalform or the re branded ones.

Promags dont feed when it's freezing outside.
C Products that I own, seemed to need break in time.
YMMV.

I really like the Brownells Colt 9mm pattern mags.  I have a dozen and have had zero problems.

No problems with my Duramags (c products) I have a bunch of ASC mags and had to file the feed lips down to get them to work, but they have been 100% since then. No experience with the metalform mags

If you have the milling jig.... just cut a slot in an Uzi magazine for ultimate indestructability and reliability. No BHO, however.
