The Second Hand Firearm - Walther PPQ 22LR Semi-Auto Rimfire Pistol is a dedicated .22 Long Rifle handgun based around the ergonomics and control layout of Walther's PPQ series. Unlike the centrefire PPQ pistols, the PPQ .22 uses a straight-blowback, internal hammer-fired operating system specifically engineered for rimfire ammunition. It combines a polymer frame, lightweight slide assembly, interchangeable backstrap system and detachable magazine in a full-size sporting rimfire platform designed for recreational range and competition use where legally permitted. The PPQ .22 retains many of the handling characteristics that made the broader PPQ family distinctive, including its sculpted ergonomic grip, ambidextrous slide-stop controls and modern accessory interface. Internally, however, Walther redesigned the action around the lower operating energy of .22 LR, resulting in a mechanically different pistol rather than simply converting the standard centrefire PPQ action.

Walther PPQ 22LR Key Features

• .22 Long Rifle Chambering: Purpose-built for .22 LR rimfire ammunition, giving the PPQ platform a dedicated recreational and sporting rimfire configuration.
• Straight-Blowback Operation: The PPQ .22 uses a simple blowback operating system in which the slide cycles directly against the recoil spring rather than using the locked-breech system found in centrefire PPQ models.
• Internal Hammer-Fired Action: Despite sharing the PPQ name and external styling, the .22 LR model uses an internal hammer rather than the striker-fired mechanism used by the standard centrefire PPQ family.
• Dedicated Rimfire Design: The slide, barrel, recoil system and firing mechanism were engineered specifically around .22 LR rather than functioning as a conversion unit fitted to a centrefire pistol.
• Polymer Frame: Uses Walther's lightweight polymer frame construction with integrated metal components supporting the slide and firing mechanism.
• Ergonomic PPQ Grip: The grip uses Walther's contoured PPQ profile with extensive textured surfaces designed to provide consistent contact around the palm, fingers and backstrap.
• Interchangeable Backstraps: The PPQ platform uses replaceable rear grip inserts on applicable configurations, allowing grip dimensions to be altered without replacing the complete frame.
• Ambidextrous Slide Stop: Slide-stop controls are positioned on both sides of the frame, supporting use by either right- or left-handed shooters.
• Push-Button Magazine Release: PPQ M2-style .22 models use a conventional frame-mounted push-button magazine catch positioned behind the trigger guard.
• Detachable Box Magazine: Uses a removable rimfire magazine designed specifically around the dimensions and feeding requirements of the .22 LR cartridge.
• Adjustable Rear Sight: PPQ .22 configurations are commonly fitted with an adjustable rear sight, allowing the factory sighting system to be mechanically corrected within its adjustment range.
• High-Visibility Front Sight: Applicable PPQ .22 sporting configurations use a high-visibility front sight paired with the adjustable rear assembly.
• Accessory Rail: The frame incorporates an integral rail ahead of the trigger guard for compatible sporting accessories where legally permitted.
• Full-Size Sporting Layout: Rather than using a substantially reduced compact frame, the PPQ .22 retains the proportions and ergonomics of a full-size modern handgun platform.
