The CP33 uses a straight blowback, hammer-fired, single-action system and a fixed 5.5 inch barrel threaded 1/2x28 TPI with a 1:14 twist. The installed Tandemkross multi-port compensator complements the threaded-barrel setup while maintaining the pistol’s balanced handling.
Its rigid aluminum upper assembly integrates a full-length Picatinny top rail and an under-barrel M-LOK slot, providing direct mounting for optics and accessories. The non-reciprocating rear charging handle keeps sight alignment stable during operation.
Sighting is fast and clear with a green fiber-optic front and a fully adjustable fiber-optic rear featuring two orange dots. The flat-faced trigger and ambidextrous manual safety levers offer consistent control, and the polymer frame includes lanyard/sling eyelets.
The hallmark of the CP33 is its quad-stack, flush-fit magazine system that delivers 33+1 capacity in .22 LR. This example includes four factory magazines, enhancing range time and training efficiency. It is made in the USA and marked accordingly.
