A Stainless Taurus Model 85 revolver with Bobbed Hammer is used by Tyrone and Vinnie throughout the film. The weapon is most noticeably seen in the hands of Vinnie when he and Sol attempt to rob the bookies. It is the first pattern Model 85 (Taurus has since changed the design of the Model 85 line).
When Vinny (Robbie Gee) threatens Bullet Tooth Tony (Vinnie Jones) he carries a Heckler & Koch P7 with black finish. It is implied that the gun, along with Sol's Heckler & Koch P9S are blank-firing 'replicas'. The prop itself, however, is a real P7 adapted to blank-fire.
Sol (Lennie James) uses a Heckler & Koch P9S to threaten Bullet Tooth Tony. The gun is also implied to be a 'replica', but they should not be able to fire full flash blanks out of the front of the barrel (like they do in the movie). The prop itself is a real P9S adapted to blank-fire, as there is no commercially-available blank replica of the P9S in real life.
Bullet Tooth Tony (Vinnie Jones) famously carries a custom two-toned "Desert Eagle point-five-oh" with a stainless frame and black slide and barrel, with the flat surfaces on the slide polished. Cousin Avi (Dennis Farina) also tries to use the Desert Eagle in a later scene. The Desert Eagle used in the movie is the Mark I model (which was never available in .50 AE) and actually appears to be the .44 Magnum version, judging by the size of the bore.

Note the teardrop safety found only on the Mark I models, which means that his Desert Eagle cannot be chambered for .50 AE (since the Mark I was never available in this caliber). It also features the stainless steel frame noted by the -S in the serial number.Error creating thumbnail: File missingTony fires his Desert Eagle.Error creating thumbnail: File missingTony shoots Boris the Blade, who refuses to die despite having an entire magazine emptied into him. Note that he fires a total of 8 rounds in this scene, which suggests that his Desert Eagle is actually a .44 Magnum model rather than .50 AE.
Unknown compact pistol
In a flashback sequence, Charlie (Jason Ninh Cao) is shown shooting Tony six times with a pistol, hence giving him the name "Bullet Tooth Tony".
I think Cozmo is right. Jericho 941 has a more 90 degree angle trigger guard whereas the ppk has a more rounded off slanted appearence which is what this piece looks like. Another possibility is a Makarov PM stainless but even that does not have the similar rounded off trigger guard. HHB3

It is seen briefly in the introduction, Boris the Blade pulls it out of his safe and cocks it.
It is also seen on a table when Boris sells Franky Four Fingers his revolver, and later it is seen again in Boris' safe when Cousin Avi, and Bullet Tooth Tony raid his home. A similar shotgun also appears to be used by one of Mickey's friends, Darren, (Jason Flemyng) to shoot one of Brick Top's henchmen at the campsite.
Vincent (Robbie Gee) buys a compact version of the SPAS 12 for the heist of Brick Top's (Alan Ford) bookie. Sol fires the shotgun twice, first to blast a hole in the wall and then into the roof. As he throws a fit upon discovering that there is no money at the bookie's place, the teller takes it from him, firing it once before retreating behind the security screens.
Various pump action shotguns are carried by Brick Top's thugs and the Pikeys, who use their weapons to ambush and wipe out Brick Top's men at the campsite.
Boris 'The Blade' Yurinov fetches an AK-74M with a GP-30 grenade launcher and magazines taped 'jungle-style' from his home after escaping capture and being hit by a car. He confronts Avi, Sol, Vinny, and Tyronne with it in a nearby bar, but never gets a chance to use it, as he is gunned down by Tony shortly after his arrival.
Boris 'The Blade' Yurinov has a collection of weapons which is shown three times during the movie: first when he is selling the S&W 681 to Tommy, when he returns a revolver to Franky Four Fingers and later when Cousin Avi and Bullet Tooth Tony break into his secret cache to look for the diamond. Feel free to ID what weapons are in there.
