The compact .40 S&W PX4 Storm is a reduced-dimension carry variant in the .40 S&W chambering. The rotating barrel mechanism is particularly beneficial in this configuration, as .40 S&W snappy recoil in compact pistols is notoriously difficult to manage — the PX4 Compact .40 S&W is considerably more controllable than comparable competing compact .40s.
