The Walther PPS is a slim, semi-automatic pistol designed for concealed carry and law enforcement personnel. Available in 9mm and .40 S&W, the PPS was introduced in 2007 and is often compared in size to the Walther PPK but shares more technical similarities with the Walther P99. Featuring a polymer frame and a short recoil-operated locked breech, the PPS utilizes a modified Browning cam-lock system for reliable performance. The PPS is highly ergonomic, with three interchangeable backstraps to accommodate various hand sizes, ensuring a comfortable grip. A notable safety feature is the QuickSafe trigger, which disables the gun when the backstrap is removed, providing a secure storage option​. The PPS M1 comes with traditional rifling, while the PPS M2 introduced in 2016 features polygonal rifling and a more refined design, including a push-button magazine release and improved ergonomics. The Tenifer-coated steel slide enhances durability and resistance to wear and corrosion, making the PPS particularly suitable for concealed carry. The PPS feeds from single-stack magazines with different capacities (6, 7, or 8 rounds), making it versatile for various carry preferences. This pistol also includes features like a loaded chamber indicator, three safeties, and steel sights, making it a reliable choice for self-defense and everyday carry.
