- Gunslinger holds the record for having missed the most Freestyle competitions at the World Finals (along with Hot Wheels), having missed three in six appearances. In an strange coincidence, all these absences came at even numbered World Finals (2, 4 and 6) while Gunslinger freestyled at all the odd numbered World Finals in which it appeared (1, 3 and 11).
- Gunslinger is one of two independently owned trucks to have advanced to the championship race at the World Finals, the other being Bounty Hunter.
- Although the truck's censorship was made official in 2017, this isn't the only time Gunslinger has been renamed "Slinger". The first instance of this censorship was in 2000, for the Rev N'Go toy release of Gunslinger, a full 17 years before the real Slinger debuted.
- The truck is most famous for his slogan, "Cocked, Locked, and Ready to Rock."
