The BHP is the only 9mm pistol a self respecting man ever needs.
It's chambered in 9mm because that's the way God and John Browning intended it.
...and mankind had not advanced in intelligence enough to invent the 40 yet
Seriously- 25 years ago I had an Argentine Hi Power, a half case of 115 grain Silvertip and a plague of Bluejays. That pistol shot well enough you could center them to about 30 paces and fill the air with feathers.
