Nice,

Here are 2 sectioned WW2 German 9x19 rounds:

Mit Eisenkern (mE) on the left and Sintereisen (sintered iron) on the right.

Also some examples of 9x19 tracer rounds and a small number of penetration improving rounds used by several police forces in Europe.

And some older examples of 1970s GeCo 9mm rounds in several guises:

Standard nato type blank firing round.
Normal GeCo 9mm round and the heavier version for the use of silencers (SD = Schalldämpfer).

In the 'hood, we call those 'vest penetrators'...

They are mainly designed to transfer energy to their target more efficiently than the standard 9mm does. In crowded areas the police want to avoid shooting any bystanders as a result of overpenetration. The rounds are also very effective tire punchers.

The green tipped version has been in use with the Dutch police for many years, being superseded by a slightly improved version with an orange tip, the 'Action NP' round.

The brass alloy, being somewhat denser, does tend to wear out the barrels quicker. This triggered a faster replacement of the current police pistol, the Walther P5. It's replacement will be the Walther PPQ-NL, the first guns were issued only a short while ago.
