Walther P99

Design work on the Walther P99 began in 1994 at Carl Walther GmbH Sportwaffen of Ulm, and the pistol was presented in 1997 as a replacement for the company's P5 and P88 service handguns. It was one of the pistols that established the modern European police-pistol template: polymer frame, internal striker, interchangeable backstraps and an accessory rail. Walther announced its discontinuation in early 2023, but by then the design had spawned an unusually large family of licensed derivatives, including the Smith & Wesson SW99 and the Turkish Canik TP9 series, which grew into one of Turkey's largest small-arms export lines.

The P99 is short recoil operated with a locked breech, using a modified Browning cam-lock system adapted from the Hi-Power. The frame is glass-fibre-reinforced polymer and the slide steel; all metal parts are Tenifer-nitrided, a process that produces a matte grey non-glare surface rated at 64 Rockwell C with roughly 99 percent resistance to salt-water corrosion, penetrating below the surface so that wear does not expose untreated metal. The pistol uses an internal striker whose red-painted tip protrudes from the rear of the slide when cocked, alongside a loaded-chamber indicator on the right of the slide. It has four internal safeties, no manual safety lever, and a decocking button set into the top of the slide just ahead of the rear sight. The magazine release is ambidextrous and built into the trigger guard. Three interchangeable backstraps were supplied as standard, a genuinely novel feature in 1997.

Trigger variants define most of the family. The original model has a DA/SA trigger with an "Anti-Stress" mode in which the striker is cocked but the trigger retains double-action length of pull; the P99QA offers a quick-action pre-set trigger, the P990 is double-action only, and the P99C is the compact version. The P99Q is a dedicated police model certified to the German police Technical Specification (TR 2008), with about 13 mm of trigger travel, a 6 mm reset, a trigger pull near 32 N and a required 10-shot group of 16 cm or less at 25 m; it is built only for police customers and is not sold commercially. A second-generation redesign in 2004 removed the trigger-guard "ski hump", added optional ambidextrous slide stop levers and replaced the proprietary accessory rail with a Weaver pattern.

The P99 and P99Q serve with police and security forces across Europe, including several German state police forces, the Garda Síochána in Ireland, the Dutch National Police Corps, Polish and Portuguese police and the Security Service of Ukraine. Finland adopted it as the PIST 2003 for the Finnish Defence Forces as well as the police, customs and border guard, and Malaysia issues it to the Royal Malaysian Police and Navy. In Turkish service the licensed Canik TP9 is a standard sidearm of the Turkish Armed Forces and the General Directorate of Security. Estonia adopted the P99Q in 2014 but replaced it with the Glock 19 after two years following reliability complaints.
