G21 mag 13rd.
Mag on the left is correct. Mag on the right, the feed lips spread (excessively) and cause the round to nose dive into the top of the chamber.
Never had a Glock mag go bad. This one might have 100 rounds on it and is one of 3 oem's that came with a G41.
I load my range mags to 10, and it would only do this on the 2nd round. Likely because that's the one with the most pressure. Rounds 1, and 3 through 10 did fine.
