1 of my 9 tested magazines will hold open on a full mag, or 1 out of 4 rounds.  Any ideas to remedy?

Newer mag with metal cut out in front and clean.

Had that prob with my G37 mags.  I removed the base plate and stretched the spring a little I have also done this with my M4 magazines when you keep 30 rounds in them for awhile they tend to make the spring compress and you can restretch them.  When I say restretch now I am not telling you to straighten them just a tug to help uncompress the spring a little.
