Since the gun jammed with several magazines, it might not be the magazine. That slide caught the extractor groove in the round it is trying to feed. That usually indicates that the slide did not recoil far enough to catch the rim and caught the groove instead as the round tried to rise.
That would point to a possible ammo problem or a too strong recoil spring. You say the gun is "super tight" and that could also slow down the slide and cause it to stop too soon. If that is the case, the gun might "break in" but I have no way to say how long that would take unless you work it manually or use an abrasive to loosen it up.
