A John V. Martz hand-built Luger chambered in .45 ACP with a long target barrel and gold-tone controls. Marked on the toggle with the JVM oval, ACP, and 45 caliber callout.
John V. Martz built his reputation on Lugers that were never supposed to exist, and a .45 ACP toggle gun sits right at the top of that list. Here's one of his hand-built pistols, marked plainly on the toggle with the JVM oval and ACP, with the caliber callout 45 stamped right alongside. That toggle marking is the signature collectors chase. It tells you Martz himself cut and fit this gun in his California shop, not a parts assembler working from his patterns.
Fitting the broad .45 cartridge into a Luger meant reworking nearly everything that matters. Martz widened the frame and magazine well, recut the toggle geometry, and rebuilt the breech to handle a round the Borchardt-Luger action was never drawn around. The result keeps the unmistakable raked silhouette while hiding a completely different machine underneath.
This example wears a long target barrel that stretches the profile well past a standard Parabellum, balanced and muzzle-heavy in the hand. The bluing runs deep and even across the barrel, frame, and toggle, with the bore bright and the rifling strong. Martz dressed the controls in gold-tone accents. The takedown lever, trigger, safety, and toggle knobs all carry that warm contrast against the dark steel. The checkered walnut grips show honest age, with the right panel softened at the edges and a few dings near the screw, and the magazine wears a wooden base.
The knurled toggle knobs, the wide trigger, the recut sear bar, all of it reads as one man's work rather than a factory line. Martz passed in 2014, which closed the book on new examples for good.
For the collector who already has the German military Lugers and wants the piece that ends the conversation, a Martz .45 is the one to chase. You're holding the outer limit of what the toggle-lock platform can be made to do.
