If your county does not have access, (which nearly half do not) they will radio in to dispatch so dispatch can call ISP and get the information along with any other outstanding warrants from other States/Counties. However, there are federal grants in the works to outfit all agencies with the same setup on their MDT's as the ISP including ID scanners, mobile tixprint machines and quicker access to NCIC. But with all this fun stuff still comes the problem that MDT unit's work about half the time if the officer is lucky due to the enormous problems with them program wise and the back order on repair.
If you have been pulled over with noted PC you MUST surrender your firearm if asked. (this only applies if the officer had PC, but have fun fighting that in court after you get tazed as it is all in the paperwork.) If there is PC and they keep it, than this is called a "Warrantless Seizure." This type of seizure is perfectly legal as long as the officer writes his report for you to be considered "dangerous" at that time of the stop. (Sound stupid I know, but its all in how he/she writes the report as they are a arm of the State and they're word trumps yours.) They can even keep it if they wish and force you to file for the return of a seized weapon in court. This will require a hearing and the State must present a burden of proof during the hearing as to the reason it was taken. From there civil suits can be filed if desired.
