The K100 is a semi-automatic, 9 mm pistol built by Grand Power s.r.o. in Banská Bystrica, Slovakia. The K100 was designed by Jaroslav Kuracina, a former weapons officer in the Slovak Army. Kuracina sketched drawings of the K100 as early as 1992, but manufacturing activities were highly restricted during the early post-Communist era. Kuracina would be forced to wait until 1996 to continue development of his design.
