The prewar Norwegian service pistol was a Kongsberg-built version of the M1911, also in .45, though with the metric caliber designition 11.25mm. I always wondered if maybe the guy was a reloader; I've never run across any Norwegian-issue .45 brass, but I'd assume it was Berdan primed. Designated *Model 1912* and *model 1914*, they had an interesting variation in the slide stop, but were otherwise pretty much identical to a standard-issue Colt M1911 pistol.
