This article or section is for a series that is Ongoing, or currently on the air and thus is a continuous work in progress. Screencaps may not be immediately available and information may not be up to date.
Detective Quentin Lance (Paul Blackthorne), Lucas Hilton (Roger Cross), as well as plainclothed officers use SIG-Sauer P226s as their main sidearm. What appear to be P226s are hurled to the ground by Arrow in "Lone Gunmen" after taking them from security guards. Huntress uses one taken from a Triad gangster in "Vendetta".
The SIG-Sauer P228 is the main sidearm of all Blackhawk Special Protection Group contractors. Diggle acquires a P228 after picking it up from a dead BSPG contractor in "Trust, But Verify".
Robert Queen (Jamey Sheridan) uses a Ruger SP101 to commit suicide in order to help Oliver survive with the remaining emergency supplies in "Pilot". Robert shows Oliver that one more bullet is left in the SP101's chamber in "Legacies".
Starling City SWAT operators use Heckler & Koch MP5A3s as their main submachine gun. It has a railed handguard, vertical foregrip and UMP-based stock, which is the same weapon used in Human Target when it was filmed in Vancouver.
A rogue Blackhawk Squad Protection Group contractor is armed with a Heckler & Koch MP5K as an alternate weapon to the Milkor MGL Mk 1L in "Trust, But Verify".
Some of the rogue BSPG contractors are armed with Colt M4A1s outfitted with vertical foregrips, red dot scopes and tactical lights in "Trust, But Verify".
A Zastava M70B1 is used by the Royal Flush Gang, except for Ace, as their main assault rifle in "Legacies". One is used by a few mercenaries in "Burned" and in "Trust, But Verify".
A Starling City SWAT operator is armed with a Mossberg 590A1 in "Pilot". It has a M4-based stock, a saddle shell holster and picatinny railings at the foregrip. The same weapon was used in "Legacies".
A Springfield Armory M1A outfitted with a riflescope, picatinny railing, riflescope, a laser sight and a JACE-100 stock is used by Deadshot (Michael Rowe) in "Lone Gunmen." It's the same weapon used by Guerrero in Human Target.
A Browning M2 is seen mounted on an Iltis Jeep in "Damaged". Given that the show is produced in Vancouver, the production crew got the Iltis instead of American-made jeeps and Humvees.
Some Daewoo K3 Paratroopers (modified with RIS and newer M249 collapsible stocks) were sold by Leo Mueller in "Damaged" to gangster before Diggle (disguised as Arrow) and Oliver (being the real Arrow) broke the arms deal twice. The weapons are actually described in the dialogue as "M249 Squad Automatic Weapons", but they are actually K3s standing in for the M249, which is common in productions filmed in British Columbia.
Used by rogue BSPG contractors in robbing armored trucks in "Trust, But Verify" by loading up with tear gas rounds. Diggle is forced to use one in the same episode by attacking a civilian truck before he turns on the contractors by using the Mk 1L against them.
Oliver uses it during his time in Lian Yu and in Starling City after becoming "Arrow". He uses it as a projectile and melee weapon. Yao Fei also uses it as his weapon in Lian Yu.
