Is Guarder G19 Lower frame compatible with WE G19?
 

I like to swap the frame of my WE G19 Custom G- Force with the Guarder one, designed for KJW G23. Is fully compatible or not? I'll do this for the Glock Logos on it

Edit: my frame is a Gen 4 while Guarder is Gen 3, I prefer Gen 3 due to the smaller release magazine button
