Sprectre Polymer80

Hi
I’m new to this forum, so my apologies if this is a question I shouldn’t ask here.
The ad selling the Sprectre Polymer80 kit doesn’t have model numbers but the parts kits below the ad show parts for 17-etc lower and slide. I am assuming, that is the line of lowers this kit matches. If that is so, is there any plans to add a Glock 19-etc.lower kit anytime in the near future? I hope so, as I already have a Glock 23 gen3 and a Glock 19 gen3. lower with an Advantage arms 22cal. slide. Would love to machine my own 19 lower and equip it with a 19 slide and parts.
