And 4 different guns.
Basically, I figured it out.
He took the 1st pistol and shot his big toe.
Then he shot the other big toe (gun count 1, hit count 2).
Then he took another gun, and shot his knee cap (gun count 2, hit count 3).
He was confused why he was still alive, so he took another gun and shot the other knee cap (gun count 3, hit count 4).
Still confused as to why he was alive and breathing, he took another gun and shot himself in the head (gun count 4, hit count 5).
