John Sullivan(Jim Caviezel) uses a police issued Glock 22 as his main sidearm through out the film but never fires it.
Sorry to be the skeptic as usual, but...are you sure it's a G22? I only ask because I'm looking at the bore in the first screencap, and it looks a bit too small to be .40; more likely 9mm, which would make it a G17 (since it's clearly a full-size Glock). I should also point out that in real life, the compact G19 is what the NYPD uses, though of course this is a movie.
Jack Shepard(Shawn Doyle) in 1969 uses a Smith and Wesson Model 36 snub nose revolver in .38 special caliber holding five shots which is accurately depicted. Also Satch DeLeon(Andre Braugher) and the man he is with have .38s drawn in 1969 at the docks after Frank Sullivan(Dennis Quaid) "drowns" Shepard. You can see them holster the .38s into cross draw hip holsters.
Used by Jack Shepard(Shawn Doyle) in 1999 as his police issued sidearm. It is classified as a P220-1 based on its wide grip and 7+1 capacity. (despite the last 8th round being given a click sound instead of a bang even though a shell is seen flying out of the gun as it locks back.)
