Which item should be entered first in the MIS field when recording a gun for NCIC?

When recording a gun for NCIC in the MIS (Misdemeanor/Exemption) field, the correct entry is "MAK UNK," which stands for "Make Unknown." This indicates that the specific make of the firearm is not known at the time of data entry. The reason this is the correct entry is that in a situation where the make cannot be identified, it's crucial to document that uncertainty instead of leaving that section blank.

Maintaining accurate and complete records is essential in the NCIC system. When the firearm's make is unknown, entering "MAK UNK" helps ensure that the record is still viable for law enforcement purposes, which aids in tracking and querying the item within the system.

While the other items—such as the manufacturer code, serial number, and owner identification—are important for a comprehensive entry, they are secondary to ensuring that the make of the firearm is indicated, even if it's unknown. This prioritization allows law enforcement to proceed with investigations while acknowledging gaps in available information.
