Formerly the Guam Shooting Sports Federation (GSSF) had existed since the 1970s,[1] which held practical shooting competitions and an annual Steel Challenge speed-shooting championships on the islands.[2]
In 2001, Guam and Micronesia were provisionally accepted as members of the IPSC,[3] In addition to civilian sport and recreation, GSSF has also hosted matches for law enforcement officers.[4] In 2010, GSSF worked on putting together a team to represent Guam in the Pacific Games and 2012 Olympics.[5]
In 2016, the Marianas Practical Shooting Association (MPSA) initially formed[6] before being formally founded in 2017, and has since represented Guam in several international practical shooting competitions.[6][7][8][9] From 2017, the Marianas Practical Shooting Association took on the IPSC representation on the islands.[1][10][11][12] Steel Challenge shooting on the island has since been hosted by the separate organization Guam United Alpha Marksman Club which is affiliated with Steel Challenge Shooting Association (SCSA).[13]
