Dek-Du
Tomás de Urizar y Cía. · Pistol · Discontinued · 1915
Also known as: Dek Du, Urizar Dek-Du
Overview
The Dek-Du is a Spanish blowback-operated semi-automatic vest-pocket pistol chambered in .25 ACP, marketed under one of the many trade names used by Tomás de Urizar y Cía. of Eibar and Barcelona. Like most Spanish pocket pistols of its era, it is a close copy of the FN/Browning Model 1906, with a striker-fired single-action mechanism, a six-round detachable box magazine, and fixed sights. Lenient Spanish patent laws of the early twentieth century allowed Eibar workshops such as Urizar to legally produce unlicensed copies of successful foreign designs, and small, easily concealed pistols like the Dek-Du were sold widely on the civilian self-defence market.

Notes
Dek-Du was a commercial brand name applied by Tomás de Urizar y Cía. alongside others including Continental, Express, Imperial, La Basque, Le Secours, Phoenix, Premier, Princeps, Puma, Union, and Venus. The firm was noted for a dragon motif used as a trademark on its grips. Specifications are typical figures for a 6.35mm Browning-pattern Eibar pocket pistol; exact factory data is undocumented.
Background
Spain's lax pre-1936 patent system protected only designs actually manufactured domestically within three years, turning the gunmaking town of Eibar into a hub for inexpensive Browning-pattern pocket pistols sold under a bewildering array of brand names like the Dek-Du.
