Dark Angel was a science-fiction series that was co-created by James Cameron and starred Jessica Alba (in her first leading role) as a genetically-enhanced super soldier who escapes as a young girl from a secret government facility and works in the underground resistance to take down the government agency that created her. The series ran for two seasons on the FOX network and co-starred Michael Weatherly.
The following weapons were used in the television series Dark Angel:
The Beretta 92FS is seen as the sidearm of the police, military, and various thug factions.
Beretta 92FS (mocked up as Beretta 93R)
Zack (William Gregory Lee) carries a Beretta 93R fitted with a suppressor when he and Max go to rescue Tinga in "Meow" (S1E19). This is actually a Beretta 92FS converted to full-automatic and fitted with a 93R flash hider and grip (this exact same gun has been used in numerous productions filmed in British Columbia).
Taurus PT92CS (modified)
In "Some Assembly Required" (S2E7), Cyborg Zack (William Gregory Lee) carries a Taurus PT92CS fitted with a custom-built compensator. This is the exact same gun that was originally carried by Mark Dacascos in the movie Crying Freeman (both productions had the same armorers).
Walther P99
The Walther P99 is carried by high-level Manticore personnel and a few others.
Vektor CP1
Logan Kale (Michael Weatherly) offers Max a Vektor CP1 early in Season 1, but she refuses. He later carries the Vektor as his main sidearm throughout the run of the show.
Glock 17
Various thugs and some police officers are seen with Glock 17 pistols. Logan's team appear to be armed with Glocks when they are ambushed in the pilot, though the police hoverdrone footage never shows the weapon clearly.
Ruger P89/KP89
The prison warden carries a Ruger P89 in "Flushed" (S1E3). Original Cindy (Valarie Rae Miller) takes it during the escape until the warden gets it back. Thugs in later episodes also use the P89, including the stainless KP89 model. Asha (Ashley Scott), head of the S1W resistance movement, carries the KP89 in Season 2.
Smith & Wesson 5906
Gerhardt Bronck (James Kidnie) carries a Smith & Wesson 5906 in "Out" (S01E10). Due to a continuity error, his weapon becomes a similar Smith & Wesson 5946 in several scenes (the 5946 is the DA-only version of the 5906).
Star M43 Firestar
Ames's Walther P99 becomes a Star M43 Firestar in a continuity error in "Harbour Lights" (S02E13).
Mauser C96 "Broomhandle"
A bounty hunter pulls a Mauser C96 on Max in the Season 1 episode "Shorties in Love" (S01E15). She later takes the gun and gives it to Logan to trace.
Jericho 941 R
Dr. Adriana Vertes (Brenda Bakke), an ex-Manticore doctor helping Logan, pulls a nickel Jericho 941 R on Max in "Female Trouble" (S01E13). Max disarms her in seconds and disassembles the weapon. In "Pollo Loco" (S01E18), X-5 serial killer Ben (Jensen Ackles) gives the nickel Jericho 941 R to Father Destry (Robert Floyd), a would-be victim, before contemptuously disarming him.
A regular black Jericho 941 R is carried by Logan's bodyguard in several episodes.
A Walther PPK/S pistol is used by Logan Kale (Michael Weatherly) in "Art Attack" (S1E12). After a gangster defenestrates a victim, Logan shoots the body and then plants the weapon on the gangster as he tries to leave the country.

Unidentified pistols
Submachine guns
FN P90
Lydecker's men carry FN P90s fitted with laser sights and flashlights during a raid in the pilot (S01E01). Jace (Shireen Crutchfield), an X5 who stayed with Manticore, uses a suppressed model in "Female Trouble" (S01E13). In "Bag 'Em" (S02E02) Manticore forces carry the P90, Alec (Jensen Ackles) and the X6s stealing a couple when they rescue Max. The P90 is the main weapon of Manticore forces in Season 2, replacing the MP5A3.
Heckler & Koch MP5A3
Lydecker's men and a few thugs use the Heckler & Koch MP5A3s. It is the standard Manticore weapon in Season 1 and police officers carry it in both seasons.
Heckler & Koch MP5K
One of Lydecker's men is seen with an MP5K in the pilot episode, as are a couple of gunmen. Col. Lydecker (John Savage) is briefly seen in the woods with an Heckler & Koch MP5K in the Season 1 finale "...And Jesus Brought a Casserole" (S01E20). Due to the darkness, it is difficult to determine which version it is.
Bronck's men carry Micro Uzis at the airport in "Out" (S1E10).
Spectre M4
The Spectre M4 is carried by a kidnapper in the pilot episode and by terrorists in "Prodigy" (S01E05)
Calico M960A
Cyborg Zack (William Gregory Lee) takes a Calico M960A Submachine Gun with a 100-round magazine and scope from a Steelhead when he goes to rescue Max and uses it in his attempted hit on Logan in "Some Assembly Required" (S02E07).
Beretta PM12S
Terrorists, thugs, and security guards use Beretta PM12Ss.
D-Technik Sa. Vz.61
Seen used by terrorists in "Prodigy" (S01E05) and used by Tinga (Lisa Ann Cabasa) in "Hit a Sista Back" (S01E18) during the apartment shootout.
Kimel AP-9
Red Series super soldiers carry Kimel AP-9 pistols with mock suppressors in "Red" (S1E09) and un-suppressed in "Rising" (S01E11).
Intratec TEC-9
A gangster pulls a nickel TEC-9 on Bronc's men in "Out"(S1E10)
Iver-Johnson Enforcer Pistol
Krit (Joshua Alba) is seen with an Iver Johnson Enforcer Pistol when the X5s are loading up early in "...and Jesus Brought a Casserole" (S01E20). He never fires it and doesn't bring it on the Manticore raid, noting that the the weapon "packs a punch, but I only have 40 rounds".
Rifles
M16A2
Military and occasionally the police carried M16A2s. There are no real M16A2s on the show, however; all of those seen in non-firing scenes were Tokyo Marui airsoft replicas. The firing M16s on the show were mostly Colt Model 715s.
Colt Model 715/Olympic Arms K4B
Whenever M16s were fired on the show, they were always Colt Model 715s or the Olympic Arms K4B equivalent. These are distinguished from the airsoft M16A2s used in non-firing scenes by the A1-style rear sight.
Colt Model 609
Police and some soldiers carry the Colt Model 609 as their main weapon. Police units carry 609s fitted with some sort of camera unit or dot-sight with a power cord leading to a backpack, while the Rangers carry stock 609s. Zack carries a Colt Model 609 carbine in the Season 1 episode " Hit a Sista Back". He later uses the weapon, along with Syl (Nicki Aycox) and Krit during the raid on Manticore in the Season 1 finale "And Jesus Brought a Casserole". X7 child soldiers carry the Model 609 as well, as do some young X5s in a flashback. At least in season 2, and probably in season 1 they appear to be mostly airsoft replicas (Probably Tokyo Maru like with the M16A2s), since they are seldom fired and are being used by minors.
Enfield L85A1
Enfield L85A1 rifles are used by the Conclave's Phalanx unit, including its leader Thula (Amy Dumas), in "Freak Nation" (S2E21).
Rocky Mountain Arms Patriot Pistol
Syl (Nicki Aycox) is seen loading up a Rocky Mountain Arms Patriot Pistol fitted with an M4 stock and carry handle in the Season 1 finale, '...And Jesus Brought a Casserole". This is one of the exact same weapons later used in 3000 Miles to Graceland (both productions had the same armorers).
AKS-74U
A gangster in "I and I Am a Camera" (S1E19) is briefly seen with a AKS-74U
M1 Garand
In Max's flashback, she remembered being trained with the M1 Garand
Heckler & Koch G3A3
A guard in the first episode is seen with an G3A3 fitted with a night-vision scope during the Manticore escape. An assassin in the same episode uses a scoped Heckler & Koch G3A3 with a rifle grenade.
Steyr AUG A1
A thug is seen with Steyr AUG A1 assault rifle in the pilot episode. Unfortunately, it was impossible to get a shot that wasn't incredibly blurry.
Shotguns
Franchi SPAS-12
Lydecker's men were seen with the SPAS-12 in the pilot episode. Police officers carry the SPAS-12 with the stock removed throughout the series
Logan uses the Mossberg 500 during the nighttime firefight in the Season 1 episode "Haven".
Ithaca 37 "Stakeout"
Logan carries a Ithaca 37 "Stakeout" shotgun fitted with a weaponlight while confronting Max in the pilot episode.
Ithaca 37 (sawed-off)
A convenience store cashier tries to pull a sawed-off Ithaca 37 when X6s raid his store for food in "Bag 'Em" (S2E2). Predictably, the X6s take the weapon and it is carried by Bullet for the rest of the episode.
A Manticore thug is seen with a Mossberg 500 Bullpup in "Proof of Purchase" (S2E3)
Armsel Protecta
A Manticore thug is seen with an Armsel Protecta in "Proof of Purchase" (S2E3) It's probably the Protecta since the series was filmed in Canada.
12 Gauge Double Barreled Shotgun
The scrap yard owner grabs a double-barrel 12 gauge when he hears a disturbance in "Borrowed Time" (S2E12)
Machine Guns
Browning M1919
A pair of what appear to be Browning M1919s are seen mounted in an armoured car in "Prodigy" (S1E7)
Grenades and launchers
M18 smoke grenade
Max (Jessica Alba) uses an M18 smoke grenade as a distraction just before the apartment shootout in "Hit a Sista Back" (S1E20). It gives off white smoke.
Unknown hand grenade
A Red Series soldier is seen with a grenade on his web gear in the Season 1 Episode "Rising". Max later pulls the pin to kill him. Despite resembling a smoke grenade, the show treats it as an HE-frag grenade
RGD-5 hand grenade
Syl (Nicki Aycox) shows Zack a couple of RGD-5 hand grenades when they load up in the Season 1 finale "...and Jesus Brought a Casserole" (S1E20).
The standalone version of the Cobray CM79LF 37mm Launcher is used by a Manticore soldier to fire a smoke grenade in "Bag 'Em" (S2E2)
Custom GP-25
A custom version of the GP-25 grenade launcher is used by Cyril, a Manticore biochemist, to fire bio-agent rounds in "Radar Love" (S2E4). The weapons is customized with a stainless-steel tubular stock and a top-mounted rail.
Other
Arcade Guns
In "Brainiac" (S2E10), a number of light guns can be seen that resemble actual firearms in the unnamed video arcade that hosts the S1W resistance group. Two appear to be modelled like a short-barrelled PSG-1 with a large scope but no magazine or magazine well.
Given the "KONAMI" logo embossed on the handguard (focussed on in a panning shot in what could be an example of product placement) and the two-player setup with two identical light guns on the same cabinet side-by-side, the arcade cabinet in question appears to be Silent Scope 2: Dark Silhouette. This is supported by how the title was a 2-player-capable game released for arcades by Konami in 2000, mounting similar light guns as those seen in the episode (the ingame player characters used modelled PSG-1 rifles as well).
