Crack under Glock 43x extractor?

[send it_hit]

Purchased brand new this week. Fired 10 rounds through it to function test. All ten were Hornady Critical Defense 115g factory loads. Disassembled to do a ".25 cent trigger job" and noticed this under the extractor. Does this need to go back to Glock, or do all 43x slides have this blemish?

Return it for refund or replacement. Nice pictures BTW.

That's normal. It's a relief cut for the extractor. Check your other glocks and you'll see the cut there also.

I see a crack ruining from the top of the extractor cut toward the bottom of the firing pin hole.
