At the same time the Bergmann–Bayard model 1910 was adopted by the Danish military.
A total of 4,840 M1910 Bergmann Bayards was initially delivered to the Danish Army.
 The pistol was produced in Belgium until 1914, when production ceased during World War I and never resumed.
 The Bergmann–Bayard was later produced in Denmark from 1922 to 1935.

Several modifications to the original design, such as an improved extractor and bolt; a screw to retain the sideplate instead of a spring-loaded catch; and a new grip design extending the full length of the backstrap to the frame were made.
The original grips were made of Trolit, a checkered plastic material similar to Bakelite.
It was, however, prone to chipping and warping, and the majority of new 1910/21 models was fitted with checkered wooden grips.

More than 2,200 Danish Bergmann–Bayard pistols were produced in Copenhagen.
In addition, most of the prewar M1910s delivered to the Danish army by AEP were converted to meet the new specifications.
These were restamped "M1910/21" beneath the Societe Anonyme Anciens Establissments Pieper on the left side of the barrel extension.
The last Danish 1910/21 models were built in 1935, but they remained standard issue for the Danish military until 1946 when they were replaced by the Browning Hi-Power.
