In order to obtain this certification, the firearm must successfully fire two rounds of ammunition that have been loaded 30% hotter than the accepted maximum caliber specification. The N stands for nitrocellulose and as you may have guessed, means that the firearm has been approved for safe use with nitrocellulose-based gunpowder. The eagle is a federal insignia in Germany and in this case is indicative of the firearm’s acceptance according to government standards. The first stamp we will discuss is the “eagle over N” that is consistent on all German firearms.

Over the years, the specific proof stamps employed by German manufacturers have varied somewhat (especially during and after World War Two), but the markings have remained fairly consistent for most of the past half-century. Though the measures seem heavy handed, collectors largely believe that the regulations did improve the overall quality of European arms in the latter half of the 19 th century. Intended to help guarantee the quality of firearms produced in each nation, proof laws laid forth a set of standards that gun manufacturers must adhere to in order to market their products. Though the European tradition of compulsory proofing (and subsequent marking) dates back to the English Gun Barrel Proof Act of 1868, Germany did not adopt a similar law until 1891.

Officially, these markings are known as proof marks or proof stamps.
