Sons of Anarchy - Season 4
The following weapons were used in Season 4 of the television series Sons of Anarchy:
Springfield Custom Professional 1911-A1
Heckler & Koch USP
Clarence "Clay" Morrow (Ron Perlman) carries the Heckler & Koch USP as his main sidearm, another holdover weapon from Seasons 2 and 3. Jax handles Clay's USP in Episode 4.12, "Burnt and Purged Away" near the climax.
The FN Five-seveN is featured prominently throughout Season 4 as one of the weapons sold by SAMCRO to the Mexican Galindo cartel. It is fired by Clay in the season premier, and later seen frequently in the hands of Galindo security chief Romero 'Romeo' Parada (Danny Trejo) and also the Niners' leader, Laroy Wayne (Tory Kittles).
Smith & Wesson 639
In "Hands" (S4E10), a Niner is seen pulling out and firing a Smith & Wesson 639 during the shootout in Laroy's club.
Smith & Wesson 659
Smith & Wesson 5906
A Smith & Wesson 5906 is used by a Lobo cartel henchman in Episode 4.7, "Fruit for the Crows".
A Glock 26 is carried in an ankle holster by Jax when he and Tara go on a retreat in Episode 4.10, "Hands".
2nd and 3rd Generation Glock 17s are seen throughout Season 4 in the hands of many SAMCRO members. Harry "Opie" Winston (Ryan Hurst) continues to use a Glock 17 as his main sidearm, and Jax also uses one (sometimes suppressed) in Episode 4.7, "Fruit for the Crows" after taking it from a slain SAMCRO Prospect.
The Beretta 92FS is used by various members of SAMCRO throughout Season 4, particularly Filip "Chibs" Telford (Tommy Flanagan). Wayne Unser (Dayton Callie) is seen firing a Beretta 92FS to create a false crime scene in "Hands" (S4E10).
"Pre-B" CZ 75
The "Pre-B" CZ 75 is used by many Russian mafiosos in "Booster" (S4E02), when they hold Jax and Opie hostage to get back their guns. It later appears in the hands of several SAMCRO members throughout the season.
In "Hands" (S4E10), a Niner is seen pulling out and firing a Taurus PT92 during the shootout in Laroy's club.
Springfield Armory XD-9 Tactical
In "Booster" (S4E02), Jax is held hostage by a Russian gangster who is armed with a Springfield Armory XD-9 Tactical.
Smith & Wesson Model 15 Snub
In Episode 4.6, "With An X", the SAMCRO Prospects are forced to use a snub-nose Smith & Wesson Model 15 Snub revolver to play Russian Roulette when Jax and Opie are trying to determine who stole a kilogram of cocaine provided by Galindo.
Smith & Wesson Model 60
The M16A2 is one of the most commonly-seen assault rifles in Season 4. It is dealt by SAMCRO to Galindo, and is also used by SAMCRO members, Galindo henchmen, and other gangs through the season. However, for some reason, the rifles are referred to as "AR-15s", implying that they are semi-automatic, even though they are shown to fire full-auto/burst. Jax uses an M16A2 at the end of Episode 4.8, "Family Recipe", while Chibs uses one in Episode 4.11, "Call of Duty".
SIG SG 552
The SIG SG 552 carbine is another assault rifle that is seen often in Season 4 and sold by SAMCRO to Galindo. SG 552s are used in Episode 4.11, "Call of Duty" by both Romeo and Luis. In Episode 4.2, "Booster", when Jax is showing off the sample of weapons to Romeo and his men, he incorrectly refers to the SG 552s as "SIG 551s", referring to the longer-barreled SIG SG 551. Although the SG 551 does later appear in Episode 4.11, used by Jax himself, the rifles seen in Episode 4.2 are definitely the shorter SG 552.
SIG SG 551
As mentioned previously, Jax carries a SIG SG 551 in Episode 4.11, "Call of Duty" during the assault on the local crew of Lobo cartel henchmen. Several of the Galindo henchmen and SAMCRO members also use them in this episode.
The AKM, one of the most common weapons sold and used by SAMCRO, again appears frequently in Season 4. It is dealt by SAMCRO to Gallindo starting in Episode 4.2, "Booster". Both Clay and Jean Carlos "Juice" Ortiz (Theo Rossi) use AKMs with synthetic furniture in Episode 4.11, "Call of Duty".
A Galindo cartel gunman is briefly seen holding an AKMS during the meeting with the Sons in "Una Venta" (S4E04).
Heckler & Koch HK416
Micro Galils are used by Galindo cartel gunmen in several episodes.
A major plot point of Season 4 is SAMCRO's attempt to sell heavy weaponry to Galindo, as per Romeo's request. The Barrett M82A1 is one of the requested weapons, appearing first in Episode 4.11, "Call of Duty" after SAMCRO imports the weapons from Ireland.
Heckler & Koch MP5K
A Heckler & Koch MP5K is used by one of Tara's kidnappers in Episode 4.10, "Hands". MP5Ks appear in several other episodes of Season 4 in the hands of both Galindo and Lobo cartel henchmen; MP5Ks with both SEF and Navy trigger groups are seen.
Heckler & Koch MP5A2
A Heckler & Koch MP5A2 was used in Episode 4.9, "Kiss", and possibly other episodes.
A MAC-10 can be seen in the hands of a man who shoots Jax after the shooting in the Mayan warehouse in "Fruit For The Crows" (S4E07).
Winchester Model 1200
Jackson (Charlie Hunnam) takes a sawed-off Winchester Model 1200 from a dead body in "Booster" (S4E02). He later fires it to the Russians. A sawed-off Winchester Model 1200 is used by Piermont "Piney" Winston at the end of Episode 4.8, "Family Recipe". It is then taken and used by Clay.
Mossberg 590 Mariner Cruiser
A major plot point of Season 4 is SAMCRO's attempt to sell heavy weaponry to Galindo, as per Romeo's request. When Romeo requests "RPGs", SAMCRO imports a number of Airtronic RPG-7 launchers, which is an updated version of the original RPG-7 fitted with an M4 stock and MIL-STD-1913 Quad Rail System rails. Jax and Chibs use these RPGs in Episode 4.11, "Call of Duty" to save Clay, Juice, and Romeo from a Lobo ambush/minefield, much to the chagrin of the Irish Kings, who requested that the weapons not be used until sold in Mexico.
Browning M2 Heavy Machine Gun
A major plot point of Season 4 is SAMCRO's attempt to sell heavy weaponry to Galindo, as per Romeo's request. Romeo requests, ".50-caliber machine guns", so SAMCRO imports several Browning M2 heavy machine guns from Ireland.
Sage Control Ordnance Deuce Revolution
Sage Control Ordnance Deuce Revolution double barrelled over and under grenade launchers (inaccurately portrayed as HE launchers) are used by Lobo cartel gunmen in Episode 4.9, "Kiss", leading SAMCRO and Galindo to realize that Lobo is better-armed than either side had anticipated.
