One possibility to consider is that other hands and staff members at the gun store handled your pistol. Being in retail for quite some time, I know customers mess with things. I would certainly think someone might have removed the slide cap and extractor pin, only to reinstall it incorrectly. No tools are required.

Customers and staff dry fire, remove slides, insert and eject magazines... I'm not saying that's what happened, but it is certainly possible, if not even probable.

Updated to add - When I first read the OP, I thought he shot 300 rounds AFTER he put the ejector back in place, and the issue happened on the first round out of the box.

Also, I'm curious if you have looked at the ammo case. I'm not super versed in this stuff, but is it possible out-of-spec ammo (overpressure) resulted in the ejector taking off?
