The foundational structure of a specific pistol model incorporates the polymer housing that holds the firearm’s internal components, including the trigger mechanism, slide rails, and magazine well. This structure is essential for proper function and safe operation, providing the grip and framework for the complete handgun.
A durable, lightweight polymer construction offers several advantages. It contributes to the pistol’s overall reliability in various conditions and reduces user fatigue during extended handling. This specific generation’s framework represents a popular choice due to its balance of proven design and aftermarket part availability. Its widespread adoption has contributed to a robust ecosystem of accessories and customization options.
