Alias was a television spy series that aired on ABC from 2001-2006. Created by J.J. Abrams (Lost), the series starred Jennifer Garner as Sydney Bristow, a young woman recruited into a mysterious government organization known as SD-6. During the course of the series, she uncovers the truth about the covert agency she works for and works to take it down with the help of her father Jack Bristow (Victor Garber), who also happens to work for SD-6.
The following weapons were used in the series Lost:
Arvin Sloane (Ron Rifkin) is seen holding a SIG-Sauer P220 in Season 3's "The Other Mr. Sloane".

Many variants of the M1911A1 are used by Sydney and other characters in the series.
Jericho 941FB Compact
Submachine Guns
MAC-10
In the premiere episode "Truth Be Told", Sydney is ambushed by gunmen who fire suppressed MAC-10's fitted with laser sights. After subduing them, Sydney picks up the MAC-10.
Heckler & Koch MP5A3
Assault Rifles
Heckler & Koch G36C
M4A1 Carbine
Non-Gun M4A1
This non guns is used in Sovogda accident by most of the characters. The stock has been removed to look like a clandestine assault rifle since the APO Task Force find these weapons in enemy territory. In a continuity error, Sloane's (Ron Rifkin) MP5K becomes a M4 non-gun when he shoots at his own thugs. These non-guns have probably been chosen because most of the shootings was filmed indoors.
