Polymer80 Compact (glock19)

[vlady]

The polymer80 is lying and you know more about their product. The front module is nitrided hence the black coating.

The rear might be 400 series S/S , the front no way.
The serialization plate 300 series S/S

The serialization plate is a thin strip of aluminum. This is what P80 customer service tells me
