At least 2 SIG-Sauer P226 pistols are seen in Season 1 in the case that was in the possession of Deputy US Marshal Edward Mars (Fredric Lane). The pistols are seen used by several of the characters throughout the season. Jin (Daniel Dae Kim) checks the SIG in "The Glass Ballerina" (S3E02).
In "The Glass Ballerina" (S3E02), a second generation Glock 17 is used by Juliet to hold Kate at gunpoint. The Glock logo can clearly be seen on the side of the gun.
Tom Friendly (M.C. Gainey) is seen with a Luger P08 in Season 3's "Through the Looking Glass, Part 1". He drops it at one point and Juliet picks it up.
The Norinco Type 54 pistol (Chinese-made version of the Tokarev TT-33) is seen among the guns in the Swan Station's armory and then is among the guns that John was transporting back to the compound in "Further Instructions" (S3E03).
Walther P38s are seen multiple times over the course of the series, starting in Season 2. Please refer to the Discussion section for a more detailed listing of the P38's use in Seasons 2-6.
In Season 3's "Through the Looking Glass, Part 1", Locke is seen taking a Smith & Wesson Model 10 from the body of deceased Dharma Initiative member lying in the mass grave.
A Mosin-Nagant M91/30 rifle is used by Mikhail (Andrew Divoff) in Season 3's "Enter 77". Mikhail's M91/30 rifle would later be used by Sayid (Naveen Andrews) in a number of episodes after "Enter 77".
AKM rifles were commonly seen in both flashbacks and on the island itself. A large collection of AKM rifles is seen in the armory housed in the bunker known as "The Swan". The majority of the AKM's found here were loaded with 20 round magazines. There is a good possibility that many of the AKM rifles in the Swan Station's armory were Romanian-made WASR-10 semi-automatic rifles.
An M1A is seen carried over the shoulder of an Other in "The Incident." The use of a muzzle brake rather than a flash suppressor (and the lack of a bayonet lug) helps differentiate the M1A from the M14.
The SKS rifle is used by Sayid in raiding the Others camp in one episode. The SKS rifle Sayid used was a Chinese SKS (note the bayonet). John Locke (Terry O'Quinn) also holds an SKS when barricaded inside a house in the episode "The Shape of Things to Come." Mikhail also uses an SKS to shoot at Desmond as he sits in a boat. One of the Jacob followers fires a SKS at the smoke monster but is quickly killed. Kate carried one on an "A-Team" mission to the Flame station and then to the Barracks in an attempt to rescue Jack. In the episode "Recon" (S6E8), Kate brandishes an SKS several times in the episode, including once as a melee weapon with the intention of swinging it by the barrel at an attacker. Several episodes later, in "The Package", the rifle is seen laying next to her.
In Season 4's "There's No Place Like Home, Part 1", Sawyer is seen carrying the L1A1, which is the British-made variant of the FN FAL made by Enfield. He is seen with it until it's thrown from the helicopter as he bails out.
The M4A1 SOPMOD is carried by Martin Keamy and the mercenaries who attack the island in Season 4's "There's No Place Like Home, Part 1" and "There's No Place Like Home, Part 2". Most of the M4's are fitted with scopes, sound suppressors and foregrips. Although never used, Sayid can also be seen carrying one after the Mercenaries were killed off before getting on to the chopper.

The M4s have been fitted various scopes, RIS foregrips and M203 grenade launchers. While fitted with suppressors as well, they seem to have no effect on the gun's report.
Heckler & Koch SR9(T)
A Heckler & Koch SR9(T) is found in the Swan station's armory by John Locke in Season 2's "Everybody Hates Hugo" (S0204).
The M1 Carbine is another one of the common weapons used on the island. Frequently carried by the "Others" as well as the survivors. The characters seen carrying the weapon include Desmond in "Par Avion", Juliet, who fires one at attackers in a boat, the young Ellie (Alexandra Krosney) in "Jughead", Ethan Rom (William Mapother) in Season 5's "Because You Left" and Claire Littleton (Emilie de Ravin) who carries it throughout Season 6.
The Heckler & Koch MP5A2 is used by US soldiers in Sayid's flashback. Also used by Martin Keamy (Kevin Durand) and the mercenaries, notably to shoot skeet on boat. Note the ambidextrous MP5-Navy trigger group.
A Crossman CO2 Air Gun is used as a tranquilizer dart gun are used at various times in the series. A notable use was in an attempt to kidnap and/or kill Sayid in Season 5's "Because You Left." Hugo also uses one to subdue Charlie in the series finale.
