P1 = Pistole 1; first post-war pistol "authorized" by the western powers for the West German military to use; a P38 by pre-war designation. Good, solid 9mm NATO pistol, but with generally horrible DA trigger, so-so (luck of the draw) SA trigger; most I have seen were carried more than they were fired. To me the more interesting ones are those designated a "P1" for export by the German government which were in reality P38s captured from the Wehrmacht but used post-war by the Kasernierte Volkspolizei, barracks police, Germans armed for police work but kept in barracks in the Soviet Zone of Occupation( East Germany), which have the East German markings...hopefully some of those will slip in with the P1s...
