The name for Heckler & Koch's infamous weapon. From the MP5 series.

The MP5SD5, chambered for 9mm, is really an MP5 with a pre-built suppressor of excellent quality. It is used most commonly by counterterrorist forces. Terrorists fear this weapon because of its clandestine capabilities and all-around great performance in the field.
