The following weapons were used in the seventh season of the television series Stargate SG-1:

Stargate SG-1 - Season 7

Handguns

Beretta M9

The most common sidearm seen in used by the SG teams (although in real life, the M9 is the military designation for the Beretta, the prop weapons used in the show are most likely the civilian Beretta 92FS).

Beretta 92FS 9mm

An expedition member fires his Beretta 92FS in "Enemy Mine" (S07E07).

Dr. Jackson (Michael Shanks) draws his Beretta 92FS on a Jaffa contact in "Birthright" (S07E10).

(Mock-up) Beretta M93R

Machine pistols with the appearance of Beretta 93Rs are seen in a number of episodes being used by US Secret Service agents, and the Trust agent Hoskins. If you look closely, you can see that they have the slide-mounted safety/de-cocker switch, whereas the 93R has it mounted on the frame. That means they're actually Beretta 92FS dressed up to resemble M93Rs (with fake forward grips and flash hiders) and probably converted to auto with drop-in units; identical guns have also appeared in Harsh Realm and I, Robot (which were both done by the same armourers who worked on this show).

Secret Service agents fire their weapons at a hologram of Anubis in "Lost City, Part 2" (S07E22) Here the slide-mounted safety/de-cocker switch can clearly be seen.

The agents continue firing, still unaware that what they are looking at is a hologram. The two other Agents carry Heckler & Koch MP5Ks.

Smith & Wesson 3913

Pete Shanahan (David DeLuise) is seen using a Smith & Wesson 3913 as his duty weapon in "Chimera" (S07E15) when Osiris leaves Dr. Jackson's house.

USAS-12 Assault Shotgun

The USAS-12 shotguns in SG1 are newer CQ versions with a modified carry handle, no front sight and shortened barrel (sometimes with a muzzle brake). The weapon is appearing on very few occasions in Season 7, usually relegated to be used by background extras.

Rifles

"Carter Special" Micro 16 Carbine

This weapon is a customized Olympic Arms K23B fitted with a Bushmaster free-floating quadruple-rail forend and a Bell & Carlson thumbhole stock. It is used with an ELCAN OS3 4x28 sight and a Beta C-Mag drum magazine with a mounted vertical foregrip and a side-mounted flashlight on the accessory rail. The first appearance is in "Avenger 2.0" (S07E09). It gets its name from Major Samantha Carter, the only character who carries it. According to the DVD commentary, it was intentionally made because blanks for the P90s were becoming increasingly expensive.

Note that the "Carter Special" has white writing on the right side of the magazine well. This is an indication that the weapon is a modified Olympic K23B (Oly's Class III AR-15 variants all have "Export & Law Enforcement Only" written in white on the magazine well).

M4A1

One of the primary weapons utilized by the Stargate teams. During later seasons they are rarely seen without any attachments, mostly being equipped with flashlights, Cobray flare launchers and laser aiming modules. A small side note for the interested reader: The lower handguard on the M4 has to be removed in order to accommodate underbarrel grenade launchers like the M203 or, in this case, the Cobray 37mm Launcher.

Daewoo K3 (mocked up as M249)

Contrary to popular belief, there are no real FN Minimi or M249 light machine guns used in Stargate: SG1 or its sister show, Stargate: Atlantis. The light machine guns used by the SG teams are actually Korean-made Daewoo K3s that have been fitted with M249 Paratrooper-style stocks and shortened barrels. Some of the K3s seen on the show also have RIS rails and vertical grips similar to those seen on the Mk 46 Mod 0.

Daewoo K3 - 5.56x45mm NATO

Daewoo K3 modified with Paratrooper stock, railed feed tray cover, railed handguard, foregrip, rail-mounted rear sight, and plastic belt box - 5.56x45mm. This is the weapon used in 2009 film Driven to Kill, shown in the making-of. These modifications are commonly found on K3s in live-action productions.
