Dreyse M1907

Lore & Background

The Dreyse Model 1907 was designed by Louis Schmeisser in 1905–1906 and marketed from 1907 onward. The pistol's most unusual feature is its cranked slide, with most of the slide lying along the top of the barrel and a short section projecting down behind the chamber to serve as the breech block. The breech block is confined within a flat-sided frame with a bridge that carries the rear sight and arrests the upper section of the slide. The recoil spring surrounds the barrel, enclosed in the frame and held by a collar engaging the front end of the slide through a spring catch. Pulling back on the finger grips at the front of the slide brings the breech block into view behind the frame.

The design was strongly influenced by John Browning's FN M1900, though the Browning has its recoil spring above the barrel while the Dreyse has a concentric recoil spring. The overall shape, grip angle and surface design, magazine release, positioning of the manual safety, and breech blocks are similar. For cleaning, the frame, receiver, and slide pivot forward on a pin in front of the trigger guard, locked in the firing position by a catch at the rear of the frame. The only major modification concerned the firing mechanism: prior to 1915, the cocked striker was held by the sear before being released by the trigger; pulling the trigger subsequently pushed the striker back before releasing it, compressing the striker spring further. Another wartime change involved a recess cut in the top front of the slide to facilitate removal of the recoil-spring retaining bush.

Reader's Guide

The Dreyse Model 1907 saw limited production but remains relatively common today, largely due to its use by Volkssturm and Volksgrenadier units late in World War II, which enabled many Allied personnel to bring examples home as war trophies. The pistol was primarily used by Austrian troops during World War I, especially officers of the Austro-Hungarian Empire, and also by officers of Imperial Germany. During World War II, it saw use by Wehrmacht troops, and near the end of the war many were issued to Volksgrenadiere and Volkssturm, often with so-called 'last-ditch' Presstoff holsters. Large numbers were brought back to the United States by returning servicemen, accounting for their availability today. A few thousand were purchased by the Czechoslovak military in 1921 and 1922 but were removed from service in 1923 due to unspecified accidents. In 1912, the pope's Swiss Guard acquired thirty of these pistols for officers and non-commissioned officers, remaining in service until 1990 when replaced by the SIG P225. The pistol also found its way to the Norwegian resistance during World War II, with examples hidden in house walls. The rear latch that holds the hinged upper part may come loose, causing the striker to move forward and ignite the cartridge; an unconfirmed civilian incident in the 1980s reportedly resulted in a shooter piercing his foot.

Did You Know?

• The firing pin projected through the rear of the breech block when the chamber was loaded, serving as an early cocking indicator.
• The entire top section of the frame and slide could be pivoted forward on a pin in front of the trigger guard for cleaning.
• The pistol was used by the pope's Swiss Guard from 1912 until 1990, when it was replaced by the SIG P225.
• The Dreyse M1907 appeared in earlier versions of the board game Cluedo, mislabelled as a revolver.

A Distinctive Locked-Breech Design

The Roth–Steyr M1907 employed a locked-breech system that set it apart from most contemporaries. Its bolt was notably long: the rear portion was solid apart from a sleeve housing the striker, while the forward section was hollow and slid snugly over the barrel. Inside the bolt, cam grooves were machined, and matching studs on the barrel engaged those grooves. When a round was fired, the barrel and bolt traveled rearward together roughly thirteen millimetres within a hollow receiver. During this brief shared recoil, helical grooves in the muzzle bushing rotated the barrel ninety degrees clockwise. Once locked, the barrel was arrested while the now-unlocked bolt continued its rearward travel, cocking the mechanism in the process. For the safety of riders in the saddle, the trigger pull was made deliberately heavy, comparable to that of a hammerless revolver. The pistol featured a fixed top-loaded magazine fed by stripper clips, fixed sights, wooden grips ending in a lanyard ring, and a four-groove right-hand twist barrel. It was chambered for a cartridge unique to this model, and rifling consisted of four right-hand twist grooves.

From Contested Prototype to Standard Issue

Czech engineer Karel Krnka developed the pistol while working for the ammunition firm of Georg Roth, building upon the earlier Roth–Theodorovic design. After a series of prototypes underwent development and testing, the final Roth–Krnka version triumphed in a 1906 military pistol competition. Because Roth possessed no weapons-manufacturing infrastructure, the Austro-Hungarian government purchased all design rights outright and placed production contracts with two state-linked factories: the Österreichische Waffenfabriksgesellschaft (OEWG) in Steyr and Fegyver- és Gépgyár (FEG) in Budapest. Between 1908 and 1914, roughly ninety-nine thousand examples were produced; the Army received 59,334 from Steyr and 38,213 from FEG, with several hundred more finding their way to the civilian market. The pistol was formally designated Repetierpistole M.7 and entered cavalry service in 1909. Despite the widely used name Roth–Steyr, the Steyr works contributed only minor refinements rather than participating in the core design.

Service Across Borders and Decades

Adopted specifically for the cavalry of the Austro-Hungarian Army, the Roth–Steyr M1907 represented one of the earliest self-loading pistols fielded by a major European power, following earlier adoptions in Switzerland, Germany, and Italy. It saw active service during the First World War. After the empire dissolved, the pistol did not simply retire: Yugoslavia incorporated it into its own inventory, and limited numbers remained in the hands of Austrian and Hungarian forces during the Second World War. Italy received a quantity of these pistols as war reparations from Austria-Hungary after 1918, and Italian troops employed them during the Second World War. The weapon also found service in Czechoslovakia and Poland. Today, a surviving example is preserved in the Bundeswehr Museum of German Defense Technology in Koblenz, a quiet testament to a design that outlived the empire that commissioned it and crossed several national boundaries before finally resting in a museum case.

Ambitions Beyond the Danube: UK and US Trials

Roth's company was eager to secure foreign military contracts and pushed the design into trials in both Britain and the United States, where larger-caliber versions were requested. In the United Kingdom, tests spanned from 1902 to 1909, evaluating pistols in 8 mm, 11.35 mm, and 11 mm calibers. The Small Arms Committee noted an unsatisfactory loading method, an excessively heavy pull-off, and too many dust openings in early models, though the Figure of Merit was praised. A 1909 Mark II test recorded an eight-round magazine, a velocity of 816.8 feet per second, and penetration of ten 13 mm boards spaced 25 mm apart at 7.6 metres. Reviewers called it handy, well balanced, and reliable in sand, with less recoil than the Webley, but flagged the absence of a safety catch. In the United States, a 10.3 mm prototype underwent endurance testing at Springfield Armory and failed the 1,250-round trial, suffering 191 malfunctions across nine ammunition types and a broken extractor.
