Operating out of his home workshop in California, John Martz is best known for his alterations and upgrades of Luger and P-38 pistols. Working with all manner of military, police and commercial Lugers as a base, the Baby Luger features a short barrel, in conjunction with a frame that has been cut and reshaped to give the signature Luger grip profile in a more compact form. This particular Baby draws components from a Mauser "S/42" code P.08 military Luger and integrates the Martz Safe Toggle Release system. Blade front and notch rear sights, with "1937" dated chamber and eagle proof extension, "S/42" on the front toggle link, and "MSTR", "JM" and "190" on the left side of the frame (the latter two hidden by the sideplate). All visible numbers match. Fitted with a set of properly sized, unmarked checkered grips and a shortened magazine with "eagle/37" proof mark and "JVM" baseplate. Includes a Hardwood display case with glass viewing window in the lid, a plaque marked "1937/BABY LUGER/MAUSER", and black velvet lining.
