Hitman: Absolution is the fifth game in the Hitman series, it is a highly contested entry due to it's many changes to the gameplay of the franchise and level design.
As far as weaponry is concerned, 47 can now dual-wield all Semi-Automatic Pistols/one-hand Submachine Guns (Revolvers cannot be dual-wielded) by picking up a second version of that firearm, this is the last Hitman game as of now with dual-wielding, 47 can freely switch between using dual/single pistols and detach/re-attach suppressors on the fly, Suppressors have reduced damage but higher accuracy (in addition to the obvious benefit of suppressed gunshots) when attached.
Hitman: Sniper Challenge was a short prelude sniping mini-game released as a pre-order bonus, however it is now included by default with the Steam version of Absolution but is missing from the GOG version, while it could arguably be considered it's own game, the fact it is incredibly short and only has a few weapons all re-used from Absolution, (With only weapon available to the player) means it has been included in this page.
The following weapons appear in the video game Hitman: Absolution:
American Derringer DA 38
The American Derringer DA 38 appears in game as the "Swiss Derringer." It is the weapon of choice for antagonist Blake Dexter's crippled son, Lenny "The Limp." On the mission "End of the Road", if Lenny is allowed to wander off, he will hide behind cover and begin to attack 47 with this gun, but he is a poor marksman and the player will likely not sustain significant damage. It can be collected and used by Agent 47 in Contracts mode.
AMP Auto Mag Model 180
The AMP Auto Mag Model 180 appears in game as the "SA .44 Auto," and is the preferred weapon of psychopathic henchman Wade. A spider engraving is found on its handle, indicating it is Wade's personal weapon. 47 uses it as his starting weapon in the level "Birdie's Gift". It is also available in Contracts mode, where it starts out with a suppressor. This coupled with its greater damage and range, make it a decent alternative to the Silverballers.
Agent 47's custom AMT Hardballers (often referred to as the "Silverballers") makes a re-appearance in the game. In the storyline mode, the Silverballers are always suppressed with the player having the freedom to toggle between single and Akimbo handguns. The Silverballers can be customized in the Contracts mode with up to three different modifications simultaneously.
While unusuable in Sniper Challenge, 47 can be seen with his Hardballers in his holsters.
Colt King Cobra
A snub nose Colt King Cobra appears in the game as the "Mustang Snub" and is the starting weapon for the Terminus Hotel level. It also is the standard sidearm for The Patriot's bodyguards in "Fight Night" plus a number of truck drivers and bar bouncers in the "Welcome to Hope" level. A special nickel plated version belonging to the corrupt sheriff of Hope, Skurky, is also present in the game, complete with sheriff's star in its wooden grip. This version cannot be collected during normal gameplay and has to be purchased in game for use in Contracts mode.

EAA Witness Limited Gold Team
The EAA Witness Limited Gold Team appears as the pre-order bonus weapon, the "Bartoli Custom". A flashy and already suppressed sidearm, it is only usable in "Contracts" mode.
Ruger Mk II
The Ruger Mk II appears complete with a external suppressor as the "Krugermeier 2-2". What the gun lacks in power, it makes up for with a larger magazine size than the Silverballer and decent accuracy, though it can only be used in "Contracts" mode.
The SIG-Sauer P226R appears, called the "Jagd P22G" ingame. The base variant is nickel plated with wooden grips and is a common sight in most levels used by guards. A suppressed unit can be found in the Vixen club. Blake Dexter's secretary, Layla, carries a custom version that has soft gold plating upon the base scheme. If collected and used in Contracts mode, it will be equipped with a soft gold toned suppressor as well. The third version, is a highly modular version issued by the Agency to its operatives. This version is dark gun metal gray with yellow accents. It can be acquired and modified for the Contracts mode as a DLC, collected in the storyline or purchased ingame.

It can be collected and used in Contracts mode, where it starts out with a suppressor.

Remington Model 700
The Remington Model 700 appears in the game as the Ilyon R700. One of the first sniper rifles one gets, the Ilyon is a perfect way to pick off targets at long range if you can forgive its un-suppressed nature. The rifle appears every so often in the campaign, in the second story of the donut store in "Shaving Lenny", the trunk of the car in "End Of The Line" and the weapons locker in "Fight Club". The in-game name is probably a reference to Ilion, New York, where Remington was originally founded.
The Sako TRG-42 appears in the game as the "Kazo TRG" in three distinct flavors. The main normal version is in green paint, and is found on Snowflake's table in "King of Chinatown", the rear dugout in "Birdie's Gift", and in the tunnel opening of "Dexter Industries". The second variant is a black painted model, commonly fitted with a suppressor. This version is found in Lenny's room in Blake Dexter's penthouse in "Blackwater Park", in the Agency sniper position in "Operation Sledgehammer" and 47 spawns with one in "Absolution." The final version is the Agency model, which can be acquired by either buying the DLC or by completing the "Hitman: Sniper Challenge".
In Sniper Challenge it is the only available firearm for 47 and can be upgraded with a faster bolt, larger magazine and the magazine well to speed up reloading, it is the Agency version and is always equipped with a suppressor.

The gunshop featured in "Birdie's Gift" features a number of displays containing both real guns the player can use, similar models only used for decoration and more low poly models that are repeated throughout the game.
