Pretty much the same as above. I had 3 legions and now have 3 Max's.
The trigger is the same that comes in a legion. Pretty much the only difference is the slide.
I reshaped and added to the top of the backstrap like a cz grip, removed the ledge at the beaver tail and shortened it. Opened up the magwell, cut off left side slide stop, GG trigger kit, keres trigger, tungsten gr, Springer mag release. Pretty much about it.
