*Please note this excerpt from http://cz-usa.com/support/faq/ The P-01 9mm (designated the P-06 in .40 S&W) was designed for LE and Military duty, but its compact size and the reduced weight due to its forged alloy frame made it ideal for discrete carry as well. Equipped with a decocker, the P-01 provides convenience for those who prefer hammer-down carry. The P-01 was the first CZ model to benefit from updated manufacturing technology at CZs Uhersky Brod factory. The components of the P-01/P-06 are completely interchangable with every other P-01/P-06, with no individual fitting required. This required some very careful re-design so that the reliability and accuracy were not impaired. Since the time of its introduction (designed in 2001, NATO-approved in 2003) the production upgrades have been rolled out to most of the CZ 75 family and several new rifle models as well. The 1913 accessory rail easily accepts any of the industry-standard lights and lasers to assist low-light use. After 3 years of some of the most aggressive small arms testing ever, the CZ P-01 won the honor of replacing the CZ 75s previously used by the Czech National Police. Reliability:  The U.S. Army Mean Rounds Between Failure (MRBF) requirement is 495 rounds for 9mm pistols. During testing of the CZ P-01, the average number of stoppages was only 7 per 15,000 rounds fired. This is a .05% failure rate or an MRBF of 2142! For many years, the P-01 carried an NSN engraved on its frame, making it the first NATO-spec pistol ever available to the public. Recently, the factory decided to upgrade the slide stop spring which in turn means the current models may not carry the NSN.
A recent HK pistol design, the 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. Variants with a conventional double-action/single action trigger have a serrated decocking button located on the rear of the frame. Variants with HKs enhanced double action only Law Enforcement Modification* (LEM) trigger have no external decocking controls. The HK Law Enforcement Modification (LEM) trigger system combines the advantages of a cocked striker component (constant level of trigger pull from first to last round fired) with a double-action hammer system. Using such an enhanced trigger system consolidates ease of use and safety into a convenient, innovative trigger operationone that reduces the chance of unintended firing. And in case of an ammunition-related failure to fire, all that is needed is an additional second or third squeeze of the trigger without the need of first pulling the slide back to re-cock the pistol. The enhanced LEM trigger system combines the reliability of a double action revolver trigger with the crisp trigger of a single action pistol. 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 with HKs enhanced double action only Law Enforcement Modification trigger 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. Extensively tested, the P30 has already been adopted by several European police agencies. Excellent weight and balance make the P30 naturally pointable, easy to control, and accurate to shoot. An open notch rear sight with luminous (non-radioactive) contrast points allows for fast and accurate target acquisition, even under poor lighting conditions. During a recent (2009-2010) endurance test, a P30 test pistol fired more than 91,000 rounds without any major component failures.
