I guess I'm lucky since I haven't had any issues with my C Products mags. I have the 25, 17, 10 and 5 round mags but use the 10 and 5 the most. I function tested all my mags with no issues but I bought these mags from 44.com last year so I figure they were made during some of the latter production runs.
