In Call of Duty Modern Warfare 2 every weapon has traits, behaviors, and attachments that make them stand out from their peers. Primary weapons like the Kastov-545 Assault Rifle for example can be heavily modified to act like a light machine gun, while Marksman Rifles can, themselves, be given short barrels and extended magazines to make them behave like hard-hitting Assault Rifles.
In the Secondary Weapon category, the X12 handgun stands out from other pistols in the game by having a fast fire rate and minimal recoil over distance. With the right perks and loadout this pistol, unlocked by reaching Military Rank 31 in multiplayer, can be laser accurate and deadly in most situations.
Best X12 Attachments
| Attachment | Pros | Cons |
| XRK LUC-9 (BARREL) |
|
|
| XRK TR9 TRIGGER |
|
|
| 9MM FRANGIBLE (AMMUNITION) |
|
|
| FTAC OL-Z GRIP (REAR GRIP) |
With the X12 featuring recoil that is more visual in its animation than it is in actual bullet deviation, attachments for this weapon are more geared towards increased movement speed and fire rate when wielding the weapon. The XRK LUC-9 barrel’s increased movement speed pairs well with the XRK TR9 TRIGGER attachment’s increased fire rate, allowing players to maneuver around the map while being able to fire the X12 faster than they could with the default trigger.
The 9MM FRANGIBLE ammunition induces a wounding effect on enemy players, slowing their health regeneration considerably and leaving them open to being finished off by the player or their teammates. The minor loss of recoil control assumed by these attachments is offset by the FTAC OL-Z GRIP, with the only lasting downside to it being a minor loss in aiming stability when aiming down the sights. This attachment arrangement allows the X12 to be fast-moving, fast-firing, and highly accurate during online gameplay.
Best Perk Package For X12
| Base Perks | Bonus Perk | Ultimate Perk |
| Double Time & Battle Hardened | Spotter | Ghost |
The X12’s fast player movement will see players constantly on the move in a variety of settings in Modern Warfare 2’s multiplayer maps. The perks players decide to use alongside the X12 will help them find the most success in-game against enemy players. The Double Time perk doubles tactical sprint’s duration and lets players move while crouched 30% faster. This is paired with the second Base Perk Battle Hardened which gives players added defense from tactical grenades like Flashbangs and Shock Sticks, while also granting immunity to SnapShot Grenades.
The Bonus Perk, Spotter, assists players by letting them spot killstreaks and enemy lethal equipment through walls, while also allowing enemy mines and trophy systems to be hacked by the player. The Ultimate Perk, Ghost, helps players remain concealed and hidden from enemy player radars. The perk renders players invisible to Heartbeat Sensors, UAVs, and Portable Radars. This Perk Package gives players the ability to offset movement-deterring equipment and status effects while remaining unnoticed by commonplace means of player detection.
Recommended Primary Weapons
The primary weapon slot has a variety of options for players to choose from when building a secondary weapon focused class for multiplayer. Assault Rifles like the TAQ-56, and M4 are highly customizable and can suit various play styles depending on the attachments they’re given. Stock and Underbarrel attachments can greatly reduce recoil while optic sights can offer lethality over range when the X12 may not be performing at full capacity. Alternatively, players could use a long-range focused sniper rifle instead, using the X12 for engagements at close and medium range before swapping to a weapon like the Victus XMR to deal with players at extreme distances.
