SWAT officers can be seen carrying Colt Model 933 carbines. Some of the rifles are fitted with Surefire M900 weaponlight foregrips, EOTech sights, and AN/PEQ-2 IR designators. Since the film appears to take place in 1995, both the weapons and their accessories would be anachronistic.
A detective is seen holding what appears to be a full sized Glock, considering the way he places his hand on the gun. It is fitted with a weaponlight, meaning it is at least a Gen 3, which would be anachronistic for the time period of the movie (1995). Note that it could also be a .40 SW Glock 22, due to the use by a federal law enforcement officer.
Glock 19
Security officers guarding an armored truck delivery draw Glock 19 pistols after being robbed by Paul Doyle (Dwayne Johnson).
Glock 34
Several law enforcement officers are armed with the Glock 34 pistol, many equipped with Surefire weaponlights anachronistic for the time period of the film (as well as the gun itself). However, due to the use by law enforcement officers, it could also be a .40 SW Glock 35.
SIG-Sauer P228
One police officer is armed with a SIG-Sauer P228 pistol.
Colt Commander
Krisztina Furton (Keili Lefkowitz) appears to pull a stainless Colt Commander pistol from her purse to fire at Daniel Lugo (Mark Wahlberg).
Kahr MK9
While in the Bahamas, Ed Du Bois (Ed Harris) is seen pulling what appears to be a Kahr MK9 from an ankle holster.
Gun Store
Several rifles and shotguns are seen in a gun store visited by the guys. Many of these were not available in 1995.
