Those are both fantastic firearms. I hope you're able to find them to buy them. None of my distributors have them for me to order, and we have none in stock at any of our 12 locations. I had today off, and wandered into a competitor to talk to a guy I know who works there. Same deal.
All of this is to say: if you find them, don't hesitate.
