is a necessity of the job due to the tight confines of an aircraft, as well as the number of bystanders. Candidates who successfully complete this training will be assigned to one of 21 field offices, where they begin their missions. Equipment Federal Air Marshals carry the following equipment: Glock 19 Gen5 9mm or Glock 26 9mm SIG Sauer P229 or SIG Sauer P239 chambered in .357 SIG; ASP 16″ expandable baton; Handcuffs. According to an anonymous air marshal, they are trained to "shoot to stop", typically firing at the largest part of the body (the chest) and then the head to "incapacitate the nervous system." In early 2020, the Federal Air Marshal Service announced the agency will be transitioning to the Glock 19 Gen 5 9mm handgun and awarded SIG Sauer the contract for ammunition.
