Just to clear this up...
There is no information whatsoever regarding any specific gun, caliber, serial #, etc. that is required to obtain a Nebraska Concealed Handgun Permit. The permit is not tied to any specific firearm, nor does Nebraska require you to give any information on what firearm you used to pass the qualification test with. Once you have obtained a valid Nebraska CHP, you can legally carry any concealed handgun, or multiple handguns, or multiple handguns at the same time, any place in Nebraska except for those places restricted by law.
The only place I know of in the state where there is any sort of registration of a firearm at all required is in the city of Omaha. As of this moment, even non residents entering the city of Omaha, legally carrying a concealed handgun as allowed by the state of Nebraska, must have whatever handgun or handguns they are carrying at the time registered with the city or they are in violation of local law.
As far as the required class and range qualification tests, I believe there are some instructors that may list certain firearm calibers, platforms, etc. that they will not allow a student to qualify with, but that is by the prerogative of the instructor, NOT a requirement of the state.
