release for normal maintenance. It is not fitted into a steel insert, only polymer, and repeated removal will loosen the tolerances, resulting in a “rattle” of that part against the weapon. The P2000 is a short recoil-operated locked breech pistol with a modified Browning-type linkless cam action with a vertically tilting barrel also employed in the USP series of self-loading pistols, as well as most modern linkless semi autos. The cold hammer-forged barrel has a polygonal profile while the slide is made from a solid bar of nitro-carburized steel. Following recent trends in modern pistol design, the P2000 makes extensive use of impact-resistant polymers to reduce weight and production costs. As with other recent Heckler & Koch pistol designs, the P2000 is modular to suit individual needs. For instance, the grip is modular with exchangeable backstraps, allowing the user to customize the pistol's grip size and feel. There is a universal accessory rail built into the dust cover in front of the trigger guard that allows for the use of tactical lights, laser pointers and other accessories. This is in contrast with the USP series which uses a proprietary H&K mounting rail that limits the types of accessories that could be used with the pistol. The P2000 is a hammer-fired pistol with an exposed spurred hammer; a bobbed hammer is optional. It has an ambidextrous slide lock and a fully ambidextrous magazine release installed in the trigger guard. Trigger variants 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 Combat Defensive Action (CDA) aka Law Enforcement Modification (LEM) mechanism is used versus a SA/DA trigger. The following options are available: V0: CDA/DA trigger system. The CDA aka LEM trigger is a dual-stage trigger that always fires from a hammer down DA mode, but has an internal mechanism that is cocked with each cycle of the action. It provides a cocked double-action trigger pull of (+4/-2 N) and an uncocked double-action trigger pull of (±5 N). V1: Same as V0, but hammer has no spur, and there is no decocker button; therefore, the only way to release the cocked mainspring is to pull the trigger over the empty chamber. V2: Same as V1 but with an increased trigger weight. The trigger pull is (±2.5 N). V3: SA/DA trigger with a decocking lever mounted at
