  • It ships with one 10-round magazine, which may be a limiting factor for buyers wanting additional capacity or spare magazines.
  • The pistol must ship to an FFL and is subject to U.S. export restrictions and applicable magazine restrictions, so purchase and transfer requirements need to be confirmed before ordering.
