The Beretta 92FS is the standard sidearm of Colonel Jack O'Neil (Kurt Russell). The pistol is seen both at his house where his son died and as his sidearm on the planet. Also seen in the hands of the other USAF team members as well as Dr. Daniel Jackson (James Spader). Beretta 92FS pistols were also used by the teenage rebels on Abydos, especially during their battle with Ra's forces.
Glock 17
All team members, with the exception of Colonel O'Neil (Kurt Russell) and Senior Airman Brown (Derek Webster), carry Glock 17 pistols. All remain holstered throughout the film with the exception of Lieutenant Colonel Kawalski (John Diehl) who, in the Special Edition of Stargate, is seen pulling it on the people of Abydos when the residents of the city closed the city doors before the sandstorm hit.
M16A1
M16A1 rifles are carried by the USAF guards in the Stargate Command Center.

Heckler & Koch HK94A2
Colonel O'Neil (Kurt Russell) and Airman First Class Reilly (Jack Moore) are armed with 9mm Heckler & Koch HK94s chopped and converted to resemble the H&K MP5A2 submachine gun. Both are fitted with Surefire flashlight forearms and telescopic sights on STANAG mounts. The same faux MP5A2 submachine guns are used by the rebelling people of Abydos (namely Skaara (Alexis Cruz) and a band of teenage rebels) later in the movie when they fight Ra's forces (the rebels had found the weapons in the team's equipment cases at their base camp).
Heckler & Koch HK94A3
Technical Sergeant Feretti (French Stewart), Staff Sergeant Freeman (Christopher John Fields), and Senior Airman Brown (Derek Webster) are armed with 9mm Heckler & Koch HK94s chopped and converted to resemble the H&K MP5A3 submachine gun (with "wide" forearm). Like the faux MP5A2 submachine guns, the faux MP5A3 submachine guns are also used by the Abydos rebels after they are found in the team's base camp.
Heckler & Koch SR9TC
Lt. Kawalsky (John Diehl) can be seen carrying the Heckler & Koch SR9TC, outfitted with the HK91 wide forearm. (Note: while John Diehl is officially credited as "Lieutenant Kawalsky," he wears a Lieutenant Colonel's insignia throughout the film.)
