What are two types of approved m9 service pistol transport methods?

Two approved transport methods for the M9 service pistol include transporting it in a locked container and using a holster. When using a locked container, the pistol must be unloaded and secured in a hard-sided case or similar, while the holster method allows for the pistol to be carried securely on the person, provided it is holstered and the individual is authorized to carry. Both methods ensure compliance with safety and legal regulations during transport.
