OK, so I know exactly nothing about how to go about this. But I have a pistol from the TV show Man From UNCLE that I'd like copied in plastic for cosplay. Just, you know, light copies that look good in a shoulder holster--non-firing, naturally. I also need one that is just like half the gun (i.e. just the handle in case we are not allowed to have a full sized pistol that "looks real") to sit in the holster. How would I go about this? Any help would be appreciated.
