Best of the duty (secondary) handguns which were actually pocket pistol size, is the Sauer 38H. They're prohibited in Canada. It's too bad. They came in 7.65 mm Browning and very occasionally 9mm Kurz, and the barrel length places them outside of the reach of most of us. The gun had the first of the cocking levers, an internal hammer, a safety which moved in the same direction as the 1911 (down is off), a very simple takedown, and were about the same size as the Walther PP. They came along too late to be able to give much competition to Walther, but they are a more advanced design.
