After a series of pistol trials, Norway adopted a copy of the Colt 1911 in .45 ACP as its standard service pistol in 1914. A license was purchased from FN (while under German occupation, interestingly) to produce the guns locally at Kongsberg, and production ran slowly and sporadically until German occupation in WWII. At that point, the German military decided to continue production for German use (still in .45 ACP, the only pistol in that caliber formally used by the German military).
The Norwegian m/1914 pistols are mechanically identical to the Colt 1911 with the exception of an extended slide release lever. They are also serial numbered on all major parts, unlike US pistols.
