Looking for yet another proverbial needle in a haystack. I'm seeking a Glock 17 Gen3 with factory Glock night sights with manufacturing number PN1750702 just above the barcode on the right of the label. Similarly to the second picture but that prefix is "PG" because it obviously states it's a Gen4. Of course I've googled and scoured the webs and figured I'd give this a shot. Willing to pay any amount within reason and travel if necessary. Anyone willing to part ways with one or can point me in the direction of someone who is, would be greatly appreciated!
