Season 1 of Colony follows Will Bowman (Josh Holloway), who after being separated from his son by walls built around Los Angeles by aliens for some time, decides to illegally travel through the wall to find his son, only to get caught in a terrorist attack. He is then forced to work for the oppressive military to stop the resistance in exchange for being able to find his son, however not knowing his own wife Katie (Sarah Wayne Callies) is working directly for the resistance.
The following weapons were used in Season 1 of the television series Colony:
Katie Bowman (Sarah Wayne Callies) pulls out a Glock 26 in "Pilot" (S1E01). She has a duel tone Glock 26 in "Yoknapatawpha" (S1E06). Will also uses the 26 to kill Quayle and two other guards.
Will Bowman uses the Beretta M9A1 while working for Homeland Security. When he first joins Homeland Security and acquires this weapon, his partner Beau (Carl Weathers) immediately identifies the pistol by name as an "M9" and stipulates that Bowman must be a veteran.
The SIG-Sauer P226R is the standard sidearm for the soldiers known as "Redhats". The rebels are sometimes seen with this gun as well, likely stolen from the soldiers. Most of the P226Rs in this season appear to be airsoft pistols, as they turn into original (non-rail) P226s whenever fired or seen in close-up.
Broussard (Tory Kittles) is briefly seen using an original SIG-Sauer P226 in "Yoknapatawpha" (S1E06). All of the firing P226s in this season are original German-made non-rail P226s, while the non-firing weapons are mostly airsoft pistols.
Operatives guarding Los Angeles known as the "Redhats" are seen with the M4A1 Carbine throughout the series. The M4s used by the Redhats are mostly fitted with EOTech holographic sights, Steiner DBAL laser aiming modules, and tactical flashlights.
The rebel force uses various shotguns like the Remington 1100. This particular model also seems to have been in the pile with the other guns discovered by Will and Beau.
A Mossberg 590 is seen in the hands of a rebel soldier. The shotgun is equipped with a flashlight, ghost ring sights, and a surefire fore end. Will Bowman also uses the same shotgun in the same episode.
