This is a factory SIG magazine built as a full-length, 10-round 9mm Luger spare. The body is steel. The extended base plate is black and is meant to sit at the bottom of a P211 or P320 grip that takes a full-length magazine, giving a solid purchase on the pad when you seat or strip the mag. Use it as a capacity-limited spare or as a replacement for a worn 10-round magazine in a P211 or P320 that accepts this full-length 9mm magazine.
