Keep the 9MM, shoot your new PX4, it is a fantastic pistol. You WILL able to get 9MM at a decent price, as the panic is already waning. Do yourself a favor. But an inexpensive single stage reloading press, and some components, and start reloading. Keep enough components on hand so that you'll be able to have 9MM or any other ammo through these panics. I was still able to buy reloading components for my various calibers even at the height of the panic.
