OP states that his 39-2 functioned with 124 gr, unknown brand, ammo.
If the ejector was damaged the problem would have been seen then.
Some of these guns were fussy about ammo. I have learned that lesson well in a few of my 39`s and 59`s.
A visible inspection of the extractor would most likely reveal any flaws.
Try not to over think this one.
