Description
Few custom firearms capture collectors’ imaginations quite like the work of master pistolsmith John Martz. Known for his inventive craftsmanship and willingness to push the boundaries of classic designs, Martz produced some of the most fascinating hybrid pistols ever created. This remarkable Martz Custom P38 with Luger-style Artillery barrel stands as a striking example of that creativity.
Built upon the iconic Walther P38 platform and chambered in 9mm, this pistol has been transformed through an extraordinary custom modification inspired by the long-barreled Luger Artillery configuration. The result is a pistol that blends two legendary German service handgun designs into one visually dramatic and mechanically intriguing piece.
The defining feature is the extended Artillery-style barrel, which dramatically lengthens the pistol’s profile and gives it a silhouette reminiscent of the famous LP08 Luger. The barrel integrates seamlessly with the P38 frame through a custom-machined mounting assembly, demonstrating the meticulous metalwork associated with Martz’s craftsmanship.
Complementing the extended barrel is a precision-adjustable rear sight assembly, mounted forward on the barrel extension. The sight features clear range markings and fine adjustment controls, providing both practical shootability and a distinctive visual character that immediately signals the pistol’s experimental nature.
The pistol retains the classic ergonomic grip frame of the P38 with traditional black grips, while contrasting polished and satin steel components, including the trigger, controls, and hammer, create subtle visual contrast against the darker finish of the slide and barrel. These small details reflect the careful attention to aesthetics that distinguished Martz’s custom creations.
From a collector’s perspective, this piece represents far more than a simple modification. It is a conversation piece, an example of the experimental spirit that occasionally emerges when skilled gunsmiths reinterpret historic firearms. By combining the engineering lineage of the P38 with the visual inspiration of the Artillery Luger, Martz created a pistol that bridges two of the most recognizable military handgun designs of the twentieth century.
Today, custom Martz pistols are increasingly appreciated for their rarity, individuality, and craftsmanship. Pieces like this one, particularly those that reinterpret historic platforms in such a bold manner, hold a special place among collectors of unusual and experimental firearms.
This Martz Custom P38 Artillery Barrel pistol offers an opportunity to own a truly distinctive example of American custom gunsmithing inspired by classic European military designs.
