Which button is located on the right side of the receiver, above and ahead of the trigger guard on the M9 pistol?

The disassembly button is specifically located on the right side of the receiver, positioned above and ahead of the trigger guard on the M9 pistol. This button serves a crucial function, as it allows for the disassembly of the pistol for cleaning and maintenance purposes. When pressed, it facilitates the breakdown of the weapon, ensuring that service members can properly maintain their firearms, which is vital for reliable performance.

Understanding the placement of the disassembly button is essential, as it differentiates it from other components of the firearm. For instance, the safety selector and slide catch lever serve different functions and are located in different areas on the pistol. The magazine release button, while also an important component, is found behind the trigger guard for quick access during magazine changes. Familiarity with the layout and function of these parts is important for effective handling and operation of the M9 pistol.
