This original Danish military holster was intended for the M/49 or Sig P210. They will also fit many other similar sized handguns. The holsters are made of cotton canvas. Another interesting aspect of these holsters is their origin. Some are made post-WWII in Denmark, and some are heavily modified WWII era British Enfield and Webley holsters.
Colors vary from khaki, brown, to green as shown in the photos.
