Well, I spoke to Glock this morning and I guess after reading this thread, my G19 Gen 4 is on its way back to Glock as I type. They sent me a pre paid label and off to FedEx it went. The Tech I spoke with did say that they would replace the ejector I had.
By the way, the number on my G19 ejector was also 336. Anyway, they said I should have it back hopefully within 10 days or so.
