Agent 47 (Timothy Olyphant)'s main weapons throughout the movie are two stainless steel-finished Para-Ordnance P18.9 1911 clone pistols, which are sometimes fitted with suppressors. Proper ID of the weapons can be obtained through various sources related to the movie, including the movie's web site (which, despite naming them as AMT Silverballers, clearly show a Para-Ordnance P18.9), DVD special features, publicity shots and a few fleeting close-up shots in the movie. Despite a scene in which 47 tells Nika (Olga Kurylenko) that his guns are .45s, the P18.9 is actually a high-capacity 9x19mm clone of the 1911.
Special
Para-Ordnance LDA
At the end of the shootout at Udre Belicoff's (Henry Ian Cusick's) place, Agent 47 grabs a Para-Ordnance LDA ("Light Double-Action") pistol from Udre's arms stash. He then uses the gun to execute Udre. A rival hitman from the Organization carries a suppressed LDA.
Special
RPD
Udre Belicoff (Henry Ian Cusick) can be seen dual-wielding two RPD light machine guns during the shootout at his palace. Udre's guns seem to have black synthetic stocks and grips instead of the usual wood and Bakelite furniture, indicating that they may be a more modern derivative of non-Russian manufacture.
Special
Heckler & Koch P2000
Interpol Special Agent Mike Whittier's (Dougray Scott) main weapon throughout the movie is a Heckler & Koch P2000 handgun with a laser pointer attachment.
Heckler & Koch USP (Custom Sport?)
Interpol Special Agent Jenkins's (Michael Offei) main weapon throughout the movie is a Heckler & Koch USP handgun with a light attachment. The weapon has tall adjustable sights, so it is possible that this is the USP Custom Sport variant. The Custom Sport was never imported to the United States, but since this film was done in Bulgaria, it's probable that the Bulgarian armorers who worked on the film did have access to one of these pistols.
Heckler & Koch MG36
A Heckler & Koch MG36 light machine gun (recognizable by the bipod fitted to the weapon) can be seen sitting on the glass table at Udre Belicoff's palace.
Blaser R93 LRS2
Agent 47 (Timothy Olyphant) uses the Blaser R93 LRS2 sniper rifle when he kills Russian President Mikhail Belicoff (Ulrich Thomsen). He is seen with the Blaser R93 at the end of the movie, using the scope to see Nika from a distance, and killing another hitman who tries to kill Nika (also armed with a Blaser R93). The Blaser R93 is 47's main sniper rifle in the first Hitman game, Hitman: Codename 47.

Arsenal AR and AR-F
One of the most commonly seen assault rifles in the movie is the Bulgarian-manufactured Arsenal AR, along with its folding-stock version, the AR-F. These are the AK-47-type rifles that are used by the Russian Alpha commandos and seen on the table and walls in Udre Belicoff's palace. Agent 47 himself also briefly uses a heavily kitted-out Arsenal AR at Udre's place during the big shootout. The AR is a modernized version of the original AK-47 which features the same milled receiver of the older rifle, but with black synthetic furniture and several other improvements. Because Hitman was filmed mostly in Bulgaria, it makes sense that the Bulgarian armorers who worked on the movie would have had easy access to weapons made in their own country, hence the frequent use of these rifles.
Interestingly, all of the Bulgarian AR rifles in the movie seem to be fitted with East German-style blank-firing adapters (BFAs) on the muzzles, which are clearly visible in all of the screencaps below.
AK-47
Quite a few original milled-receiver AK-47s can also be seen in the film. They are used first by the rebel fighters in Niger at the beginning of the movie, and again by the Russian Alpha guards at Udre Belicoff's funeral (it is most likely that their use is supposed to be ceremonial, in much the same way that M14 rifles are used by U.S. Honor Guards).
RPG-7
An RPG-7 can be seen in the hands of a militiaman in Niger early in the film.
AKS-74U
FSB agents throughout the film (both plain clothes and SWAT) use the AKS-74U.
Heckler & Koch MP5A3
During the shootout at Udre Belicoff's palace, Agent 47 arms himself with two Heckler & Koch MP5A3s, fitted with tri-rails, that are sitting on the table. It's a notable goof that he never slaps down the bolts after he loads in the magazines, yet a split second later, both guns are fully cocked and he begins shooting with them.
Many of Mikhail Belicoff's bodyguards are also armed with MP5A3s, though theirs do not have the tri-rail.
Uzi
Uzi submachine guns are used by several of Mikhail Belicoff's bodyguards throughout the film.
Unknown M1911 derivative
Another nickel/stainless 1911 with pearl or ivory grips is briefly seen in Udre Belicoff's palace.
Walther WA2000
Agent 47 trains a Walther WA 2000 sniper rifle at Agent Smith's head when he meets with him at Moscow. The WA2000 is 47's favorite sniper rifle.
FN P90
The Interpol SWAT team led by Agent Whittier is armed mostly with FN P90 submachine guns. Another P90 can be seen briefly on the table at Udre Belicoff's palace.
Special
FN F2000 Tactical
Some of the Interpol SWAT operators also use the FN F2000 Tactical bullpup assault rifle, fitted with EOTech red dot sights.

The first weapon that Udre Belicoff shows off to his clients is a Bulgarian Arsenal Shipka submachine gun, which fires the same 9x18mm ammunition as the Makarov. However, he claims that it is a "Kedr 9mm compact", referring to the Russian-made Kedr PP-91. Agent 47 remarks that it's actually a "Chinese copy", but in reality, the Chinese do not manufacture a copy of the PP-91.
Both Udre and Agent 47 have misidentified this weapon. A close inspection reveals that the gun they both handle is most definitely a Shipka and not a Kedr PP-91. Pictures of both weapon types are shown below for comparison's sake.
Makarov PM
During the weapons deal at his palace, Udre Belicoff (Henry Ian Cusick) points a Makarov PM at a hooker's eye and then fires it at Agent 47. Being ignorant of guns in general, despite being an illegal arms dealer, Udre claims that the Makarov PM fires .22LR ammunition: yet another in a long series of factually false statements by Belicoff. To be fair, there was a .22 LR conversion kit available for the Makarov ([1]), but it seems unlikely that Udre would know this.
M4A1 with M203 Grenade Launcher
During the shootout at the hotel, one of the Russian Alpha commandos who gets shot by Agent 47 in the elevator is armed with an M4A1 Carbine with an M203 grenade launcher.
Later at his palace, Udre Belicoff shows off another M4/M203 combo (which appears to be the exact same prop gun used by the commando earlier in the movie), but inaccurately describes it as an "M203 with under-barrel grenade launcher"(!?!) as well as claiming that the weapon fires 7.62x39mm ammunition, even though it actually fires 5.56x45mm NATO ammunition. This is one of the many factually inaccurate statements that Udre makes about the weapons he is selling, as Agent 47 himself points out.
Special
Micro Uzi
A Micro Uzi is one of the weapons used in the shootout at Udre Bellicoff's palace.
Special
Dragunov SVD
An assassin attempting to kill Agent 47 uses an SVD Dragunov. If you watch closely, it jams on the second shot, yet fires the third seconds later.
Taurus PT92
Taurus PT92 pistols are used by the other hitmen from The Organization in the fight scene on the train. The guns are modified with some type of custom-built compensator.
