The actual pistol prop used by most Alliance characters is the same as those used by the Alliance in Stargate SG-1, the South African built Vektor CP1. These pistols were pulled from the market due to the fact that their safety mechanism has a fault tendency and the weapon has a habit of discharging on its own. Also present during there attempted takeover was a second pistol given to Colonel David Telford by Kiva. It appears to be based on the SVI Infinity, a pistol based on the Colt M1911A1 pistol.
