Handguns act as tertiary weapons in the single-player campaign or terrorist hunts, and as secondaries in multiplayer. All pistols have unlimited ammo.
Beretta 92FS
The Beretta 92FS appears in the game as the "92FS", can be modified with silencer, laser sight and high capacity magazines like the other pistols. It can also be found on an L.V.P.D. officer's body in one of the levels. The safety on the 92FS is always on.
The H&K Mk 23 Mod 0 appears in the game as the MK.23. Can be modified like all the pistols. It is the most popular pistol on online servers. It has front cocking serrations like the Phase II Prototype of the Mark 23.
The Desert Eagle Mark I appears simply as "Desert Eagle" in the game. It can be modified with laser sight and high capacity magazines, but cannot accept a sound suppressor. It incorrectly holds 7 rounds (suggesting that it is the .50AE Mark XIX), despite this particular model being only chambered in .357 Mag and having a 9-round capacity. It's recoil is greater than all other sidearms except for the Taurus Raging Bull. The Raging Bull and Desert Eagle often get one shot kills with a less than perfect shot.
The Taurus Raging Bull revolver appears in the game, it can only be modified with laser. Some terrorists carry the Raging Bull as a secondary weapon. The one used in the game is most likely chambered for .480 Ruger due to its 6-round cylinder capacity and massive power.
The Glock 18C appears in the game and can be modified with a laser sight. For some fairness, the magazine size is limited to 10, whereas the standard Glock 17/18/34 magazine holds 17 rounds. Can fire in semi-auto and full-auto modes. Appears as "Glock 18", however the compensator cuts can be seen clearly on the barrel.
The Heckler & Koch MP5N is the starting submachine gun in the game. Can be modified like all weapons in the game. Fires in 3-round burst, but is modeled without that option on the selector; the model is basically an MP5A3.
The Heckler & Koch MP7A1 with a 40-round magazine is in the game, and can be modified with everything. The MP7A1 is the secondary weapon for Jung when he isn't using a G36C and for Walter when he isn't using a Mk.48 machine gun.
The H&K UMP45 appears in the game as one of the most powerful submachine guns. It is always fitted with a vertical foregrip and can be modified like the other SMG's. Its only drawback is the 25-round magazine.
The Ingram MAC-11 is in the game and like the other weapons, it can be modified. It is incorrectly shown firing from a closed bolt instead of open-bolt.
The AK-47 is used by enemies in the Mexican levels, it can be modified with a laser sight, ACOG, reflex scope, suppressor, and rifle scope. Interestingly, it is modeled with the less curved 5.45mm magazine of the AK-74 despite being a 7.62x39mm weapon.
The Heckler & Koch XM8 appears in the game as the "M8", assuming that in the Rainbow 6 universe the US Military has adopted the rifle and thus dropped the "X" prefix. It can be modified with everything. Very popular weapon on multiplayer servers.
The Tavor TAR-21 is in the game as the "MTAR21" even though the MTAR-21 is actually the micro version, it can be modified with everything. It is very popular on online servers due to their high rate of fire. Players who have taken a liking to the Tavor have often been called "MTARDs".
The FN SCAR-H CQC appears in the game as "SCAR-H CQC" and is fitted with a non-removable vertical fore-grip. Can be modified with everything. In game it has an incorrect 30 round magazine. The actual magazine capacity is 20 rounds.
The Benelli M3 Super 90 appears in the game as the "M3". It can be modified with laser sights, rifle scope and reflex sight. It is portrayed as a pump-action shotgun, although the real-life one is select fire.
The Franchi SPAS-12 appears in the game, it can be modified with laser sights, rifle scope and reflex sights. Just like the M3 Super 90, it is restricted to pump-action mode.
The M26 MASS (Modular Accessory Shotgun System) appears in the game as "XM-26 LSS" (LSS standing for Lightweight Shotgun System) and is only used in a stand-alone configuration. In reality, the M26 is more often used as a under-barrel mount system for M16/M4-type weapons. The actual weapon is a manually-operated straight-pull bolt-action shotgun and does not have a semi-auto or automatic capability as depicted in-game. It can be modified with a laser sight, a rifle scope, or a reflex sight.
The Heckler & Koch PSG-1 appears in the game as the only semi-automatic sniper rifle. Has a 5+1 round capacity. Like the other sniper rifles, it can be modified with a 12x Scope. Appears as "PSG1".
The Heckler & Koch MG36 is frequently used by enemies in the game, it can be modified with Reflex sight, laser sight, rifle scope and better buttstock.
The M67 hand grenade appears in the game as the standard fragmentation grenade. The player must take care using it, as it can easily cause fratricide if misused.
The M18 smoke grenade appears in the game and can be used to conceal the movements of the player and the team, the team being able to use thermal imaging to see through the smoke. Some enemies will also use these as well on occasion.
The M84 stun grenade appears in the game being used by members of the Rainbow team during "flash and clear" dynamic room entries, being tossed into a room to disorient enemies so they can be eliminated. Enemies will occasionally use them as well.
The AN/M14 incendiary grenade appears in the game as the "incendiary grenade", and can set enemies on fire with an orange "mist", but disrupts thermal vision.
In some scripted events, the terrorists fire rockets at the player. It is unknown what weapon model being is used, because only the rocket coming towards the player can be seen. One of the team members says that it is an RPG.
