The CZ 455 Thumbhole Yellow is designed for target shooting. The Thumbhole Yellow model features the CZ Flyweight Trigger mechanism which gives the option to set the trigger travel and pull weight. The addition of a fluted barrel reduces the overall weight, while maintaining the same high accuracy and consistency achieved with the standard varmint barrel.

The thumbhole stock is made of laminated wood in yellow and black. The trigger guard and the magazine base are made from a solid block of aviation duralumin and are anodized yellow.
