This page needs lots of work. It's nice we have screencaps for it now, but gun page links do NOT go in the heading, and stand-alone gun pictures are needed. Formatting is a bit too sloppy for IMFDB standards. -MT2008
It is but I'm really happy to see it up. Humanzie3
Thomas Murphy (Kevin Costner) carries a pair of M1911s which he wields akimbo during the Casino heist. At one point in the movie, he looses these guns after being aressted, and later recieves a replacement from his friend Jack (Howie Long).

Smith & Wesson Model 29

Beretta 92FS
The Casino security guards are carrying Beretta 92FS during the Casino heist shoot out.
Also, during the final shootout at the warehouse, some of the Police officers surrounding the area are armed with Beretta 92FS.
Beretta M93R
Franklin (Bokeem Woodbine) uses a Beretta M93R during the Casino heist. The weapon appears to be converted to full auto, and Franklin fires it with no concern of innocent bystanders.
Walther P99

SIG-Saur P226

Single Action Army
Murphy gets pulled over by an officer carrying a Single Action Army, which he uses when he challanges Murphy to a quick draw duel.
The front sight philed off [of the SAA} for faster draw. The guy playing this sheriff is a quickdraw shooter, and removing the front sights is a pro technique if you can quick draw for real. - Gunmaster45
Smith & Wesson Model 28 Revolver
Smith & Wesson Model 686 Revolver
Smith & Wesson Model 686 Revolver 2 1/2" Barrel with Hogue Grips.
Shotguns

Remington 870
One of the Casino security officers fires a Remington 870 at Murphy and company.
Mossberg 500
Just before the final shoot out in the warehouse, Murphy (Kevin Costner) is given a short barreled Mossberg 500 with rear and foreward pistol grips. He uses the weapon to shoot Michael (Kurt Russell) after SWAT shows up, and breifly uses it to shoot at the SWAT team members.
Sub Machine Guns
FN P90
Hamilton (Ice-T) uses a pair of FN P90s wielded akimbo during the warehouse shoot out. In one of the more cool looking (and kind of stupid) scenes, Hamilton rides a zip line upside down, spraying both FN P90s at the SWAT officers. He is quickly gunned down, of course, for exposing himself as such an easy target.
Jack uses a Ruger MP9 during the final shootout in the warehouse.
Assault Rifles
Ruger Mini-14
Some of the Casino security (or undercover LVPD) are armed with Ruger Mini-14s during the closing scenes of the Casino Heist. Two of the officers exchange fire with Murphy and Michael's group as the retreat to their get a way helicopter.
Custom Rocky Mountain Arms Patriot Pistols
During the casino heist, Gus (David Arquette) and Franklin (Bokeem Woodbine) use strange-looking compact assault rifles. One of these weapons is also used near the end of the movie, when Murphy (Kevin Costner) uses one for the first part of the warehouse shoot out. These weapons are custom-built Rocky Mountain Arms Patriot Pistol "carbines". They were clearly built by fitting Patriot Pistol upper receiver/barrel assembles to the lower receiver/telescoping stocks of some other M16 carbine variants, mostly likely the XM177 or Model 654. The armorers then added M4-style carry handles and 100-round Beta-C magazines. Guns similar to these have also been seen in Congo and Soldier (ironically, the latter is another movie that starred Kurt Russell).
(Fake) Colt XM177
Hanson (Christian Slater) and Michael (Kurt Russell) use M16 carbine variants that are mocked up to resemble Colt XM177 during the the casino heist. Michael never fires his weapon at any of the security guards, instead shooting the glass above a group of persuing guards. Michael then passes his gun to Murphy (Kevin Costner) as the group makes their escape to the helicopter.
All of these rifles are fake XM177 rifles which seem to have been built from other AR variants. The real XM177 has a slab-side receiver, which only Michael's gun has (at least when he's in the elevator). The rifles used by the other robbers have both M16A2-style receivers (forward assist, brass deflector, and M16A2-style rear sight) and Model 715-style receivers (forward assist, brass deflector, and M16A1-style rear sight). This means that they're probably other AR carbine variants with chopped barrels and fake XM177 flash hiders fitted. Most of the Hollywood "XM177s" seen in movies are just like these (see also The Rock, for instance).
Light Machine Guns
M249 Paratrooper SAW
During the final shoot out in the warehouse, Jack (Howie Long) uses a M249 Paratrooper SAW against several SWAT officers. After Jack is gunned down while trying to save Murphy (Kevin Costner), Murphy picks up the M249 and uses it for his last stand.
Misc.
Las Vegas Police Officer's P226/M1911
