Thanks to Dickson L. for sharing these with us. This is the H&K P8 A1. Looks like a USP doesn’t it? It is a modified USP for the Bundeswehr. The safety/decocker has been modified. The P8A1 safety is raised parallel for fire and lowered for safe. H&K also uses land and groove rifling instead of the polygonal rifling seen in ordinary USPs.
Here is a photo of a regular USP. Notice the safety design is different and the S/F markings indicating safe and fire are opposite from the P8.
