METRIC HANDGUN

Metric Handgun encompasses handgun cartridges defined by metric designations rather than traditional Anglo naming conventions, reflecting European and international measurement standards used from the nineteenth century through the modern era. This category spans a wide range of calibers and systems, including early rimfire and pinfire types, revolver and self-loading pistol cartridges, and later commercial and military developments such as 9 mm and 10 mm class ammunition. The material represented illustrates the broad adoption of metric nomenclature across civilian, police, and military handgun ammunition worldwide.

Items in this category include live rounds, blanks, dummies, sectioned examples, experimental loads, and boxed material across multiple generations of design. Variations in case construction, headstamps, projectile form, priming systems, and packaging document differences between national standards, manufacturers, and periods of production. From a collector and research perspective, metric handgun ammunition provides a framework for comparative study of international handgun development, allowing documentation of how measurement systems, industrial practices, and cartridge concepts evolved across borders and time.
