I own 6 Taurus semi-autos and not one of them has any problem including the magazines. I ordered an extra 12 round mag for my Millennium G2 9mm and for some reason this particular magazine won't work correctly. It is a factory Taurus mag just like the ones that came with the gun when purchased new.
The mag I received will load to capacity (12 rounds) but will not work in the gun unless there are only 7 rounds or less in the mag. I'll load the mag, insert it into the gun, try to rack the slide but the slide just stays back. It's like the rounds are glued down or something. I can't even force the slide shut. But, if I only load up to 7 rounds, the magazine will work perfectly. So, I guess I bought a 7 round magazine instead of the 12 rounder I paid for.
I've taken the mag apart, cleaned it, inspected it, I can't figure out why it's not working like it's supposed to. 12 rounds will go in, but it's inoperable at anything past 7. ??????
