Colt Model 1903 Pocket Hammerless

The Colt Model 1903 Pocket Hammerless is a .32 ACP (7.65mm Browning) caliber, self-loading, semi-automatic pistol designed by John Browning and built by Colt Patent Firearms Manufacturing Company of Hartford, Connecticut.
Despite the title "hammerless", the pistol is fired by action of a hammer striking and driving a firing pin into a center-fire cartridge's primer. The hammer is covered by the rear of the slide.
The "hammerless" designation was merely an advertising designation pointing out the pistol's particular suitability for concealed carry.
Special features include a serrated slide to prevent slippage during manual cycling of the slide and two safety mechanisms (a grip safety and a manual safety).
The grip safety is a spring-loaded piece making up the back strap of the pistol. The grip safety, though not solely restricted to them, was a typical feature of Colt automatic pistols.
A magazine safety was added on later models; this feature prevents the pistol from being fired with a round in the chamber and the magazine removed.
In October of 1944, the design was modified with the addition of enlarged sights, an increase in the number of slide serrations from 17 to 19, allowing 1911 tooling to be used. The .32 ACP model also was changed from a blued finish to a parkerized one.
Metal finish is blued or nickel, and some special-order finishes such as engraved, silver- or gold-plated.
While the FN Model 1903 pistol design is related to the Colt Pocket Hammerless, it is physically larger due to its chambering in the 9×20mm SR Browning Long cartridge.
The Model 1908 was introduced five years later in .380 ACP (9mm Short) caliber.
It is nearly identical to the Model 1903 except for the bore diameter and the magazine, which holds seven rounds (one fewer than the Model 1903).
Grip panels are black checked hard rubber, checked walnut, or special order materials (ivory, mother of pearl, inset medallion). Sights are fixed, although the rear sight is drift-adjustable for windage.
General officer models were often engraved with the officer's name. Recipients include generals Dwight D. Eisenhower, Omar Bradley, George C. Marshall, and George S. Patton.
Patton's Model 1908 was embellished with three (later four) stars on the grip panels to denote his rank.
They were issued with a fine-grade leather holster, leather pistol belt with gold-metal clasp, rope pistol lanyard with gold-metal fittings, and leather two-pocket ammunition pouch with gold-metal fasteners.
They came in russet or black leather (depending on service and regulations) and were made by Atchison Leather Products or Hickok. A cleaning rod and two spare magazines were also included.
Generals were issued the Model M in .380 ACP, until 1950, when supplies ran out. At that point, they were substituted with .32 models until their replacement in 1972.
The Pocket Hammerless was replaced by the M15 pistol made by Rock Island Arsenal in .45 ACP.
Approximately 570,000 Colt Pocket Hammerless pistols were produced from 1903 to 1945, in five different types. Some were issued to U.S. Army and U.S. Air Force general officers from World War II through the 1970s.
Outside the US, the Pocket Hammerless was purchased by various countries and used during the World Wars.
The Shanghai Municipal Police issued the M1908 to its officers in the 1920s and 1930s and it was a popular model with police in the U.S. such as the Boston Police Department.
In addition to lawful owners, many gangsters of the pre-World War II era favored the Model 1903 and Model 1908 because they were relatively small and easily concealed.
It is said that Al Capone kept one in his coat pocket and Bonnie Parker used one to break Clyde Barrow out of jail after smuggling it into the jail by taping it to her thigh.
Bank robber John Dillinger was carrying this model of pistol when he was shot by FBI agents outside the Biograph theater on July 22, 1934, and another famous bank robber, Willie Sutton, had one when he was captured by police in Brooklyn on February 18, 1952.
This pistol was also used by an Indian revolutionary, Chandra Shekhar Azad, in 1931, when he committed suicide to avoid capture by the Indian Imperial Police at Alfred Park in the town of Allahabad in India.
The Colt Model 1903 Pocket Hammerless was used in the assassination of SS-Obergruppenführer Reinhard Heydrich (top Nazi officer) in the Protectorate of Bohemia and Moravia on May 27, 1942, in Prague. The assassination was successful due to wounds he suffered from the bomb thrown into his car.
Former Japanese Prime Minister Hideki Tojo used a Colt Model 1903 to attempt suicide shortly before his arrest for war crimes on September 11, 1945. Tojo was convicted at trial and was executed on December 23, 1948. Tojo's pistol is on display at the MacArthur Memorial in Norfolk, Virginia.
In Warlord Era China, some cottage artisans created pistols that were visually similar to the Colt Model 1903, but dissimilar in mechanics (such as the lack of a grip safety and a heel magazine release).
The Model 1908 was the pistol of choice for Raymond Westerling, a captain in the Royal Netherlands East Indies Army. He was known for orchestrating counter-guerrilla operations and for his alleged war crimes during the Indonesian National Revolution.
His personal Colt is now on display at the Nationaal Militair Museum in Soesterberg, The Netherlands.
