V is the ABC television series which is a remake of the original 1983 miniseries. As in the original, an alien race comes to Earth which a promise of cooperation and superior technology, but their real intentions are slowly revealed to a handful of humans.
The following guns were used in ABC's remake of V:
Erica Evans' duty weapon from episode 2, "There is No Normal Anymore", onwards was a Gen 2 Glock 19. A Glock 19 was also used by Georgie Sutton (David Richmond-Peck) in "A Bright New Day" and "It's Only the Beginning".
Glock 26
A Glock 26 is used by Erica Evans in episode 12, "Red Sky".
Smith & Wesson 3913 "Ladysmith"
A Smith & Wesson 3913 "Ladysmith" is used by Erica in "Welcome to the War" after her Glock gets chopped in half. It is only used in this episode; afterwards, she resumes using a Glock.
Ruger KP89
A Ruger KP89 is used by Ryan as his main sidearm, seen first in "It's Only the Beginning". After a period without using it, Ryan is seen with it in episode 9, "Heretic's Fork".
SIG-Sauer P226
A nickel SIG-Sauer P226 is used by Cyrus to threaten Ryan in "A Bright New Day". Ryan uses the pistol for a while when he disarmed Cyrus. A blued version is given to Val by Ryan to defend herself against the V soldier, though it looked like a Walther P99 when he passed to her. It's hard to tell, but it also appears that Agent Dale Maddox (Alan Tudyk) is carrying a P226 in the Pilot episode.
Kyle Hobbes (Charles Mesure) uses a Walther P99 in the face-off before the escape in "Welcome to the War". It's also his main sidearm.
Jericho 941
A nickel-plated Jericho 941 with a suppressor, is used in the attempted "assassination" of Marcus.

Kyle Hobbes (Charles Mesure) gives a CZ 75B to Jack which is then used by Jack to shoot the human sniper who takes out Alex in "We Can't Win", which becomes his main sidearm. A nickel CZ 75 is also used by Peter Combs (Craig Fraser) in "It's Only the Beginning."
Colt Lawman Mk III
Alex Caruso is armed with a Colt Lawman Mk III in "We Can't Win" before Erica convinces him to drop it.
Submachine Guns
Heckler & Koch MP5A3
A Heckler & Koch MP5A3 with a Surefire flashlight grip was seen in the Pilot in the hands of an anti-V resistance fighter. In "Welcome to the War", FBI SWAT operators are also armed with the MP5A3.
Assault Rifles
M4A1
M4A1 carbines are carried by National Guardsman in their New York deployment in the Pilot episode. However, they should be armed with the M16A2 as it is their standard rifle.

A Remington 870 was used in the Pilot by an anti-V fighter. Never used, and also seen in "Heretic's Fork" held by Mrs. Thompson.

Unknown Rifle
Mr. Thompson is seen with an unknown bolt-action rifle in "Heretic's Fork". Froma closer look at the bolt, it appears that the rifle is a sporterised Mauser 98 bolt-action rifle.
Others
