magnumforce,
The H&K semi-auto that you're asking about, is not an MP5 - which is a sub-machine gun. You're describing the H&K 94 series carbine, in 9mm. There is an LE marketed version of the MP-5 that has the semi-only fire-control pack, but you didn't indicate you've got the departmental backing (or badge) to justify this latter restricted arm. So, we're back to the H&K 94.
Shotgun News & The Gunlist are excellent sources for classified ads for such firearms. Don't expect to find a bargain on the H&K 94 or the semi-auto SP-89 pistol, as they're in very high demand by both conversion shops and people like yourself that recognize a quality product.
