Interesting - flat points on the rounds - we still use 9mm parabellum (Luger) which has a more pointy tip to it - special Cop issue perhaps?
We use a mixture of Browning GP35, Glock 17 and Sig P228 in our trade and the ammo's all the same.
Though being a retro fanatic, I still rate the best handgun I've used was the (very) old walther P38 that my granddad gave me and which I used to good effect on Op Granby (1st Gulf war to the rest of you). Sadly it was pinched by a Yank after the fighting was done with.
