A Walther PPK/S is put in one of the money bags, where it mysteriously turns into a Kahr K9. Another continuity error is that the NYPD officer showing Walter Garber how to use the PPK/S indicates that the safety was on when it was really off, and vice-versa.
SIG-Sauer P226
A SIG-Sauer P226 is used by Bashkim (Victor Gojcaj), one of the hijackers, when he and the rest of the gang attempt to flee.
Glock 19
NYPD officers in the subway tunnels and above ground are armed with Glock 19 pistols.
Kahr K9
The Walther PPK/S that was hidden for Walter Garber (Denzel Washington) magically transforms into a stainless steel Kahr K9 when he confronts Ryder (John Travolta). Washington is seen flipping the safety "off", a feature Kahr pistols do not have (Edit: This statement is not entirely accurate. Some Kahr pistols do in fact have safeties. The K9 series, however, does not).
A SIG SG 552 assault rifle with tri-rails is used by Bashkim during the hijacking.
SIG-Sauer SSG 3000
A NYPD sniper is shown aiming a SIG-Sauer SSG 3000 rifle fitted with a Harris bipod and what looks like a Leatherwood/Hi-Lux Camputer scope at the hijacked subway car.
M4A1
NYPD ESU teams are seen carrying M4A1's into the tunnel as they prepare to engage the hijackers.
