Collectors and enthusiasts of the iconic Mauser C96 'Broomhandle' pistol are encountering significant fitment challenges with modern reproduction holster stocks. Reports from the community indicate that these aftermarket stocks, often sourced from international manufacturers, frequently fail to align properly with original pre-war commercial C96 models. One user described receiving a reproduction wood holster stock set where the metal dovetail, designed to slide into the pistol's grip, was incorrectly T-shaped and incompatible. This issue necessitates extensive manual fitting, such as filing, to achieve even a rudimentary fit, a process that risks damaging the historic firearm and significantly diminishing its collector's value. Another collector noted a similar problem with a stock from a different vendor, requiring considerable material removal (1-2mm) from the repro stock metal before it could be mounted smoothly. The consensus among experienced collectors is that the root cause lies in the manufacturing process of these reproductions. Many current aftermarket parts are several generations removed from original molds or specifications, leading to a cumulative loss of detail and dimensional accuracy. This 'copy of a copy' phenomenon results in parts that are often out of tolerance by critical millimeters, making a proper, drop-in fit nearly impossible. Experts advise extreme caution when attempting to modify either the reproduction stock or, more critically, the original firearm itself. Modifying the pistol's grip to accommodate a poorly fitting stock can irrevocably harm its historical integrity and market value. Instead, some recommend seeking out 'new old stock' (NOS) parts or investing in higher-quality reproductions that adhere more closely to original specifications. The issue highlights a broader challenge in the vintage firearms market: the availability of affordable but dimensionally inaccurate aftermarket components. While these parts may seem like a cost-effective solution for collectors, the time, effort, and potential damage involved in fitting them often outweigh the initial savings. For the discerning collector, preserving the originality and value of a historical piece like the Mauser C96 demands a meticulous approach to sourcing and fitting any replacement or accessory parts.
