I can't see if they are genuine Glock but if they are call Glock and maybe they will replace them for free or sell you new. Glock is one of the best CS gun manufacturer. Your gun is covered with a lifetime warranty. How do I know, my sister gave me a 19 and it needed a new frame, Glock did it for free. But ck with them before anybody else.

Are you sure it was the mags that caused the stoppage? I have magazines from different manufactures including Pmag. So the mags may not be the issue. It could be improper grip or even a problem with the gun itself. More time at the range may reveal the exact problem.How many rounds were fired being new at shooting is a common cause with new gun owners.Did this happen with both mags?

I was taught 70/30, strong hand(the hand you grip the gun with), and then the support hand. I'm not saying that this IS the problem just maybe the issue.
