Battlestar Galactica (2004) - Season 3
The following weapons were used in Season 3 of Battlestar Galactica (2004):
Colonial Standard Military Sidearm (FN FiveseveN)
From Season 2 to the end, this weapon became the standard Colonial Military sidearm. It is a slightly modified original-run FN FiveseveN. It keeps the underbarrel explosive launcher. This changeover allows for real semi-automatic fire and makes use of the existing stores of 5.7 x 28mm blank ammunition. The explosive launcher was muzzle loaded, and was featured in the second season episode "Valley of Darkness," but not prominently afterward.
A Number 5 or Doral (Matthew Bennett) holds a Vektor CP1 to President Baltar's head to force him to sign death warrants in "Precipice" (S3E02). Felix Gaeta (Alessandro Juliani) pulls the Vektor CP1 on Baltar in "Exodus, Part 2" (S3E04).
Several of the resistance fighters including Anders carry unmodified FN FiveseveN pistols.
Heckler & Koch MP7A1
Another weapon used by the Colonials is the Heckler & Koch MP7A1. The major addition to the weapon itself is an ELCAN optical sight rather than a red dot or basic iron sights.
The Beretta M12 is one of the weapons recovered from the hidden cache during the escape from New Caprica.
Beretta CX4 Storm
From Season 2 to the end of the series, the Beretta CX4 Storm is the standard long gun of the Colonial Marines on board the Galactica and the Pegasus. The weapons themselves have various attachments including a rail system with red dot sight, flashlight attachments, and a custom flash hider.
Norinco Type 84S
The Norinco Type 84S is another weapon seen in the hands of a Resistance fighter after its recovery from the arms cache on New Caprica. Not clear what the exact weapon is but it may have been a folding stock Norinco 84 given the shape of the magazine making it a 5.56mm weapon and not a 7.62mmx39.
A Daewoo K3 (fitted with RIS and KAC vertical grip, to imitate an FN Minimi SPW is glimpsed briefly in the Razor movie, used in the final assault on the Cylon Basestar and also seen in the arms cache in Season 3's "Exodus, Part 3".
This distinctive South African shotgun Armsel Striker makes a few appearances in the series but not in its primary role. Instead, as in numerous shows, it's shown as a grenade launcher.
Cobray 37mm Launcher
On New Caprica, this single shot grenade launcher is picked up from hidden weapons cache.
