If you are looking for a functional radar gun, check out the new mod by @opus49 that uses this radar gun model. Thanks for the good work Opus!
I don't actively visit this site anymore. You can do anything you want with the model/texture including reuploading to other sites, repackaging, and just about anything else you can think of.
The ProLaser 4 Radar Gun is here! Combine this mod with Albo's Traffic Policer for great RP.
Installation:
Use OpenIV to copy all four files into mods > update > x64 > dlcpacks > patchday8ng > dlc.rpf > x64 > models > cdimages > weapons.rpf
(Optional) Install Claude_III's mod to allow marksman pistol use in a vehicle. https://www.gta5-mods.com/weapons/driveby-marksman-pistol
Thanks to Narobic for letting me know about the driveby mod!
