Supressed/silenced pistols?

How many did you guys find? I managed to find only 3 through my playthrough.
One in chapter 10 next to a dead body, 2 in chapter 11 with one being on a barrel in a human area, and the other being near another dead body in a spider area.
I wish we could of gotten it a bit earlier

oh... I already missed at least one of them. Hopefully there will be human for me to test for it. Or add NG+.
