After market glock slides serial number questions

[TacticalDan]

I was wondering if I change my slide on my glock19 for a after market s lol ide with a time cut do I have to have it serial number engraved or does it come with its own serial number and I have to register it as well?

what does a glocks slide have to do with a serial number???

My glocks all have frame and slide matching numbers.

The slide/barrel is non registered parts.
No worries there,

The Glock frame is the registered firearm. The rest is just noise.
