I'll add that Fiocchi also makes a nice inexpensive brass cased boxer primed 9x18 round. Usually runs around 16-18 bucks per 50 depending where you go.
I have had good luck with Fiochi ammo. My P64 has eaten several hundred rounds without a single issue. I use other calibers of Fiochi quite a bit. It is cheap, reliable ammo. It can be incredibly cheap when on sale with free shipping.
