A device designed for the Walther P22 pistol increases ammunition capacity by adding to the standard magazine. These devices, typically constructed from polymer or metal, attach seamlessly to the base of the existing magazine, providing a more substantial grip and faster reloading during shooting activities. An example would be a +5 extension, which would add five additional rounds to the factory magazine capacity.
Enhanced firearm control and reduced reloading frequency are key advantages offered by these add-ons. The extended grip surface provides a more secure and comfortable hold, particularly beneficial for individuals with larger hands. This improvement translates to better accuracy and control, especially during rapid firing. The increased ammunition capacity minimizes downtime spent reloading, crucial in competitive shooting or self-defense scenarios. Historically, extended magazines have played a role in both military and civilian applications, often reflecting the ongoing need for a balance between firepower and practicality in firearm design.
