Kate Macer (Emily Blunt) and other FBI agents carry a third generation Glock 19 as their main sidearm, the former notably using hers during the shootout at the Juárez-El Paso border crossing.
A Beretta 92FS can be seen in a Delta Force operator's holster during the shootout at the border crossing. A Sonora cartel member is later seen wielding a Beretta.

The MK23 can be differentiated from the USP series by the raised sections of the front and rear of the slide at the point the sights are situated, from the curved underside of the front of the frame and also the threaded hole in the front of the wider, elongated trigger guard (for installation of a Wilcox or similar locking LAM unit) which you can see clearly in this still. Also the frame on a Mark 23 is significantly wider before the integrated rail than on a USP. Though it is hard to identify in the film, this enhanced publicity still helps, as well as a brief side shot in the film, detailing the unique Mark 23 trigger guard.Error creating thumbnail: File missingAlejandro (Benicio del Toro), while carrying his Gen 4 Glock 17, (if you look closely) can actually be seen with the Mark 23 in his vest holster, suppressor attached. Nifty continuity and foreshadowing. This could not have been mistaken for a similar USP, as it has an ambidextrous safety lever, which can clearly be seen on its left side.Error creating thumbnail: File missingAlejandro confronts Fausto Alarcon (Juan Cedillo) and his family.

Submachine Guns
Heckler & Koch MP5A3
Alejandro (Benicio del Toro) uses a Heckler & Koch MP5A3 with a Gemtech suppressor, KAC railed handguards and an Aimpoint sight. An unsuppressed MP5A3 with a Surefire forend is used by a cartel gunman during the border crossing shootout.
FBI Agents Kate Mercer (Emily Blunt), Reggie Wayne (Daniel Kaluuya) and Phoenix Police Department SWAT officers use M4A1 Carbines with EOTech 553 sights and/or Aimpoint CompM2 CCO sights and foregrips during the film's opening raid in Chandler, Arizona. During the US-Mexican border scene, DEA Agent Steve Forsing (Jeffrey Donovan) and Delta Force commandos also use M4A1 Carbines with EOTech 553 sights and foregrips. Mexican Federal Police officers, Border Patrol Officers, and cartel members carry M4A1s with detachable carrying handle rear iron sights and older A2 rounded handguards. At least two Phoenix SWAT officer wield M4A1s with black Magpul MOE furniture and ACOG scopes in the first minutes of the film and are carried as well by Delta Force commandos, most notably by the team leader (Dylan Kenin) during the night raid to the tunnels in conjunction with the standard M4A1. Its possible these may be airsoft replicas as well like the G&P M4 MOE CQBR but these rifles feature 14.5 in barrels.
Matt Graver (Josh Brolin) uses a Daniel Defense M4A1 with a foregrip, Magpul PMAG, EOTech 553 sight, and SureFire M720V RAID flashlight as his main weapon.
During the border shootout, Delta Force commandos use what are likely airsoft replica G&P M4 MOE CQBR rifles. Border Patrol and ICE Agents are also seen with these rifles as they are guarding a large group of captured immigrants.
An AK-103 rifle (likely an American semi-auto clone such as the Arsenal SLR-107FR) is used by a cartel hitman disguised as a Federal police officer (or a corrupt Federal police officer doing jobs for the cartel) during the border crossing shootout. A similar rifle is also seen in Silvio's (Maximiliano Hernández) home.
