33 round 9mm mags, 15 round .40 mags, 17 round 9mm mags, even those with +4/+6 extensions on them, yes, I would bet my life on them.
I had 3 22 round .40 mags. After a few hundred rounds through them, they started to have some issues. About 600 rounds in, they were one or two bobbles every 2nd or 3rd mag. Glock replaced 2 of the 3. One of those never had an issue, the other one had the same problems after about 600 rounds. Tweaked springs, had custom springs made, tuned followers. If I can not run 200 rounds straight through a pistol, it is not streetable to me. Even then I run 50 rounds a quarter through every defensive firearm. So, 22 round .40 mags, 2 of the 3 could not pass the 200 round test...sold them all.
