The Prototype Pocket Revolver: An Early Korth Design
The history of firearms is filled with groundbreaking innovations, and few names stand as prominently in the revolver world as Willi Korth. Known for his masterful craftsmanship and relentless pursuit of perfection, Korth’s firearms have long been considered some of the finest revolvers ever produced. Among these remarkable designs lies a lesser-known, fascinating piece of Korth’s legacy—the Prototype Pocket Revolver. Initially mistaken for a live-fire version of the Gas-Korth revolver, closer inspection revealed an entirely new lock mechanism, distinct from previous Korth designs.
The Origins of the Prototype
Following the passing of Willi Korth, German firearms law required his widow, Kriemhild Korth, to transfer all essential firearm components to an authorized individual. A trusted gunsmith was entrusted with the frames, cylinders, barrels, and various other parts.
In the spring of 1998, the author of this study received a tip from Kriemhild Korth about a gunsmith who still possessed some of these old revolver parts. The gunsmith, having no practical use for them, turned over the entire collection. Among the components were the pieces of an incomplete revolver—a unique prototype.
The Challenges of Restoration
Initially, a gunsmith specializing in long guns attempted to assemble a functional revolver from the seemingly matching parts but was unsuccessful. One of his modifications included annealing the side plate to drill a hole intended for a transfer lever pressure spring. This alteration was later reversed by welding and smoothing the hole before refinishing the surface with a hand polish and re-bluing. The restoration efforts continued, addressing inconsistencies such as an unnecessary threaded hole behind the trigger, which was sealed with a set screw. Additionally, a trigger replacement—likely from the 20xxx series—required further modification to fit the smaller frame.
Through careful integration of later-series replacement parts, the prototype was restored to functionality. However, the only existing documentation validating its origins was a photocopy of an evaluation conducted by Max Leyerda.
Firearm Testing and Evaluation
Dynamit Nobel AG’s Werk Stadeln Technical Service conducted an evaluation of this revolver on October 16, 1962. The examination confirmed that the firearm was a Korth prototype chambered in .32 Long (7.65mm) with no assigned serial number.
Barrel and Sighting System
- Barrel Length: 55mm
- Barrel Construction: Screwed into a solid sleeve integrated with the cylinder frame, secured by a 2.5mm contact collar.
- Final Production Plans: Intended to have a permanently integrated barrel, unlike the prototype’s removable design.
- Sight System: Non-glare design with an extended front sight and a rear notch.
Cylinder and Locking Mechanism
- Cylinder Length: 35mm
- Capacity: 5 Rounds
- Material: Solid EC 80 Steel
- Locking: A deep locking shaft (2.6mm compared to Smith & Wesson’s 1.6mm) ensuring secure positioning.
- Removal Mechanism: A button-activated bayonet lock enabled easy cylinder detachment for maintenance.
- Strength and Security: Unlike Smith & Wesson revolvers, the Korth design ensured the cylinder remained firmly locked during firing.
Trigger and Internal Mechanisms
- Double-Action and Single-Action Capable
- Locking Mechanism: Prevents accidental hammer release unless the trigger is fully engaged.
- Return Springs: Steel wire-formed springs provided resilience and longevity.
- Firing Pin: Independent from the hammer and return spring-secured within the frame.
- Trigger Pull: Notably smooth, with reduced resistance.
Grip and Aesthetic Features
- Material: Teakwood grip panels with refined checkering.
- Attachment: Secured with a steel-bushed screw, preventing lateral movement.
- Final Production Plans: Intended to be replaced with walnut grips.
Innovative Engineering: A New Lock Mechanism
The lock mechanism of this prototype demonstrated a significant departure from conventional revolver designs.
The firing pin safety (33) ensured drop safety by blocking the firing pin unless the trigger was fully engaged. This principle, which was introduced with this prototype, remained a standard feature across all subsequent Korth revolvers. The interaction between the cylinder lock, firing pin safety, and other internal components formed a complex but highly effective safety and locking system.
A major improvement over competing designs was the depth of the cylinder lock, which ensured that the cylinder would not unlock upon recoil, a common issue with some Smith & Wesson revolvers.
Removable Cylinder System
One of the most distinctive features of this revolver was its removable cylinder. This design allowed for straightforward maintenance and cleaning. Unlike traditional revolvers that required partial disassembly, Korth’s approach enabled the user to detach the entire cylinder assembly with the press of a button.
However, an early design flaw meant that if the cylinder was misaligned when pressing the release button, it could become jammed. This was later corrected in future models by ensuring the locking pin only protruded when the cylinder was correctly positioned.
Significance and Legacy
This prototype marked an essential evolutionary step in Korth’s revolver development. Several design principles introduced in this early model became defining features of later Korth revolvers. The revolver’s robust EC 80 steel construction, innovative locking mechanism, and refined ergonomics were all indications of Korth’s pursuit of excellence.
Additionally, its planned calibers—including .22 Long Rifle, .32 S&W Long, .38 Special, and .357 Magnum—demonstrated Korth’s intent to appeal to a broad range of users, from sport shooters to law enforcement.
Final Thoughts
The Prototype Pocket Revolver stands as a testament to Willi Korth’s ingenuity and engineering prowess. Despite being an unfinished concept, its influence on Korth’s later designs is undeniable. The firearm’s carefully crafted lock mechanism, durable materials, and unique cylinder system established a new standard in revolver construction.
While it may not have made it into mass production, this prototype remains an invaluable piece of firearms history. Its role as the “forefather of all Korth revolvers” cements its place as one of the most significant experimental firearms in modern revolver development.
