Infallible Pistol was a .32 ACP caliber handgun manufactured by the Davis-Warner Arms Corp during the early 20th century.
When Warner Arms Co. could no longer get the Schwarzlose Model 1908 pistols from Germany, they had .32 pocket pistols made in the United States in three variations. the front sights and the grips that there was a conscious effort to imitate the outline of the Schwarzlose.
The guns were called the “Davis-Warner Infallible”, and their trademark was “Blocks the Sear”, a reference to the way the safety worked. Unlike the Schwarzlose M1908, the Davis-Warner guns are fairly conventional, striker-fired, blowbacks, using a breechblock rather than a slide, though, since Browning had patented the idea of an auto pistol slide with an integral breechblock.
They had one serious drawback. At the back of the guns there is a small lever and a push-through pin. If the shooter disassembled the pistol and forgot the turn that lever the right way or forgot to push the pin all the way in, the breechblock would be stopped only by a small projection and could come back in his face. The guns were not “infallible” and the company soon went out of business.

The Campo-Giro was a semi-automatic pistol, chambered for the 9mm Largo cartridge, which saw service in the Spanish military. It is named for its designer, Colonel Don Venancio López de Ceballos y Aguirre, Count of Campo-Giro.[1]
Background
[edit]
Venancio López de Ceballos y Aguirre was born in 1856 in Peñacastillo, Santander. He attended the Academia Militar de Caballería (Military Cavalry Academy) from 1876 to 1879, and graduated as a second lieutenant and first in his class. In 1881 he enrolled in the Academia de Estado Mayor (General Staff Academy), becoming staff lieutenant in 1885. He held a number of positions until 1893 when he was posted to Melilla. In 1894 he was promoted to major and the following year posted to Cuba as Chief of Staff for the Matanzas brigade. He was based there when the US Navy bombarded Matanzas during the Spanish–American War. He was appointed Chief of Staff for the 3rd Division, 1st Corps and decorated for his Cuban service. On his return to Spain he was elected to the Spanish parliament and in 1905, one year after his first patent, placed on the retired list. In 1909 he was promoted to lieutenant colonel, and in 1911 returned to active duty. He ended his career in 1912 as aide-de-camp to General Fernando Primo de Rivera, uncle of the future Spanish dictator.
Development
[edit]
Campo-Giro obtained his first patent in 1904 for Una pistola automática de calibre 9mm. de nuevo sistema (“An automatic pistol of 9mm calibre of a new system”). He followed this in 1911 with a patent for a self-loading carbine. In 1912 he obtained a registered design for his pistol. In November that year lodged another patent for Una pistola sistema Campo-Giro con amortiguador del choque en el retroceso, para los calibres 11,25, 9mm largo, 9mm corto y 7,65mm (“A Campo-Giro system pistol with a shock-absorber for recoil in calibre 11.25, 9mm largo, 9mm Kurz and 7.65mm”).
The pistol was adopted for the Spanish army in 1912 as the Pistola Campo-Giro de 9mm Modelo 1912. The previously issued Bergmann–Bayard pistol which was found unsuitable for military use during the early Moroccan campaigns was however still retained by those troops who had been issued with it, the 9mm Largo cartridge having been judged a success. Early examples were manufactured by the Oviedo armoury. The design proved both modern and sound and the pistol saw widespread use during extended trials.
