From memory, the 9-ring is 4 or 5 inches, the 10-ring is 3". At 25 yards.

A colleague of a mate at the Bureau qualified with a Glock 22, and all ten rounds touched at the 25 yard stage. He kept the target on his wall as a trophy.

From memory, despite what the link says (200) the real passing score for instructor was 260 one handed, 280 two-handed.
