The P30 is a polymer framed semi-automatic handgun by Heckler & Koch, available in 9×19mm Parabellum.
The P30 is a fully ambidextrous polymer framed short recoil–operated locked breech pistol with a modified Browning-type linkless cam action with a vertically tilting barrel.
Technically, the P30 is similar to the Heckler & Koch P2000 pistol; the differences are in exterior appearance and ergonomics. The basic design is derived from the Heckler & Koch P2000 and Heckler & Koch USP Compact pistols.
The P30 is a hammer-fired pistol with an exposed spurred hammer; a bobbed hammer is optional. It has ambidextrous slide release locks and a fully ambidextrous magazine release installed in the trigger guard, on both sides. Various trigger and cocking systems offer the possibility of converting the trigger firing mode from one type to another. Several variants are available based whether the LEM (Law Enforcement Modification) trigger (H&K’s double-action only) mechanism is used versus a SA/DA trigger.
