It is cheaper to go with a Spinta or other aftermarket option. I have a Spinta on one, a LithocoreX on another,
a LoneWolf on my 10mm and a Rockslide on my 45AARP. I can't remember which I have on my subcompact but I usually run it with an OEM Glock 19 Gen 4 slide. The CL frame is one of my favorite Poly80s to shoot, its what the Glock 19x should have been, IMO.
