FN P90 Personal Defense Weapon

The P-90 is the standard issue rifle for the SGC since the mission to P3X-888, as well as the standard issue rifle for the Atlantis expedition. Like other guns, it is primitive compared to Goa'uld, Wraith, and Ori weapons, but it is more than capable of piercing the armor worn by Jaffa, Ori soldiers, and Wraith warriors. According to Jack O'Neill, it is a weapon of war, designed to kill the enemy, and holds better offensive capabilities than the staff weapon. Daniel Jackson and Teal'c have also begun using the weapon in recent years.
