HK's P30 is a modern police and security pistol that combines function and safety. Ergonomic features include a special grip frame with interchangeable backstrap inserts and lateral plates" allowing the pistol to be individually adapted to any user. Ambidextrous controls include dual slide releases and magazine release levers. P30S models have an ambidextrous safety lever mounted on both sides of the frame. S models are available in conventional double-action/single action trigger mode and have a serrated decocking button located on the rear of the frame in addition to the two safety levers. A Picatinny rail molded into the front of the frame makes mounting lights" laser aimers" or other accessories easy and convenient. The extractor doubles as a loaded chamber indicator providing a subtle tactile and visual reminder of a loaded chamber.
