Porter (Mel Gibson) uses a blued Smith & Wesson Model 27 4" with S&W factory combat grips for the majority of the film after buying it in a pawn shop. It is not a Smith & Wesson Model 29 as previously mentioned, as the diameter of the muzzle and cylinder chambers is clearly too small to be .44 Magnum.

His lack of gun safety is pretty obvious as he hands him the gun with the hammer cocked and his finger on the trigger.Error creating thumbnail: File missingLeft: Porter swings open the cylinder and spins it. A ratcheting sound effect is heard even though there is nothing for the cylinder to ratchet against. Right: Porter examines the gun like a real pro by pointing the muzzle at himself.Error creating thumbnail: File missingAfter doing some flashy twirling, Porter hands the shop owner the Model 27 back to make a purchase. No FFL, no handgun liscence, no waiting period, no way...Error creating thumbnail: File missingPorter searches his wife's house with his Model 27 at the ready. He has a "USMC" tattoo on his shoulder, so you'd assume he'd know how to clear a room. Instead he does what is typically done in films and wanders around the house with the revolver cocked and pointed at the ceiling.Error creating thumbnail: File missingA Model 27 with regular grips is seen in Detective Hicks' (Bill Duke) holster.Error creating thumbnail: File missingPorter holds his Model 27 on Val in the hotel room.Error creating thumbnail: File missingPorter shoots Val in Rosie's (Maria Bello) house.Error creating thumbnail: File missingPorter uses a pillow to muffle the gunshot as he executes Val. This is movie fiction, as a pillow would not properly suppress a handgun, especially a revolver. It is also pointless since three rounds are fired before this.Error creating thumbnail: File missingPorter holds his Model 27 on the Detectives before handing it to them outside the "Outfit's" building.Error creating thumbnail: File missingArthur Stegman (David Paymer) holds a Model 27 on Porter in the back of a Taxi cab before he takes it from him.Error creating thumbnail: File missingPorter fires the Model 27 in an awkward akimbo stance along with a Beretta 92FS at the Triads, unloading about 13 rounds from his six shot revolver. For whatever reason he chose to put the heavier recoil handgun in his non-dominant hand, a poor choice in the real world.Error creating thumbnail: File missingPorter fires the two guns through the floor of the Triad van. You can see he is simply dry-firing the gun as no muzzle flash is seen, likely a safety procaution for firing blanks at such close proximity.Error creating thumbnail: File missingA close up of the guns firing, with excellent shots of the gun's markings.Error creating thumbnail: File missingPorter rolls out from under the van and shoots the Triad driver.Error creating thumbnail: File missingPorter holds the Model 27 on Pearl (Lucy Liu).Error creating thumbnail: File missingThe gun clicks empty. That's the inconveniance of movie guns, they can fire off a ridiculous amount of ammunition but never have a bullet left when you really need it.Error creating thumbnail: File missingInternal Affiars officers show off Porter's original Model 27 to Det. Hicks (Bill Duke) and Det. Leary (Jack Conley) after Porter left the gun (covered with their fingerprints) at the scene of Val's murder, along with one of their badges.
At one point in the movie, Porter is attacked by a group of Chinese gangsters he had robbed earlier, two of them are armed with M3 "Grease Guns". They clearly have a charging handle making them the older M3s, not M3A1s.
