What is the first step in the field strip/disassembly of the M9 service pistol?

The first step in the field strip or disassembly of the M9 service pistol involves clearing and unloading the weapon. This is a critical safety measure that ensures there is no ammunition in the chamber or magazine before proceeding with any further disassembly. It is essential to prevent accidental discharge and to ensure that the firearm is safe to handle.

By fully clearing and unloading the weapon, you remove any potential danger that comes with handling a loaded firearm. This process typically includes visually and physically inspecting the chamber to confirm that it is empty, as well as removing the magazine, if one is present. Once this step is completed, the operator can confidently move on to subsequent steps in the disassembly process, knowing that the firearm is safe to work on.

Other steps like releasing the magazine, removing the slide, or removing the grip panels all come after ensuring the weapon is clear and unloaded. They are important in their own right, but they assume that step one—the safety check—has already been performed.
