By the time Bergmann found a production subcontractor in AEP for the Spanish order of 1903 Bergmann pistol, the Spanish had added a few new changes to their order, which became known as the Model 1908. In addition to filling the Spanish production, AEP also sold the guns on the commercial market fairly successfully.
In 1910 an order was placed by the Danish government, with a few additional changes to the design (improved mainspring, magazine well cutouts to better grip the magazines, larger grips, etc) which became the Model 1910. AEP would institute these changes into their commercial guns as well as producing 4800 for Denmark. Production continued for civilian sales during German occupation in World War One, but ended after the war due to a lack of demand.
When Denmark began to run low of spare parts and wanted more pistols in 1921, they made yet more changes (primarily a much better set of grips and a non-reversible locking block to simplify reassembly) and put the new Model 1910/21 into production domestically. These would be the highest production evolution of the design, and are very nice sidearms, despite being bulky, heavy, poorly balanced, and low capacity in comparison to the other handguns then available on the market.
