- "Available by default, the silenced MP-446 is balanced evenly as an effective sidearm."
- ― in-game description
The MP-446 Viking is a Russian semi-automatic pistol designed and developed some time in the 1990s.
In Tom Clancy's Splinter Cell: Conviction, a suppressed version of the MP-446 is available for use by the player in the Kobin's Mansion mission and onwards. It has two marks without the reflex sight and a magazine capacity of 17 rounds. With the laser sight and match grade ammo, it can be accurate at long ranges. Its major downside is lack of stopping power compare to other pistols: only headshots will kill in one hit; anything else will require at least 4 hits. Before the introduction of the Five-seveN, the MP-446 is the best silenced sidearm available for players who like to mark and execute, because the MK.23 only has 2 marks maximum. After the Five-seveN becomes available, the MP-446 still retains some viability as despite having one less mark, it can mark and execute at slightly longer ranges. The MP-446 is available mainly via weapon stash; the gun is very rare, carried by one 3E strike team member in the Lincoln Memorial mission and, bizarrely, a couple of the Secret Service agents killed near the end of the final mission (who in reality actually use the FN Five-seveN)
|Reflex Sight||400 points|
|Laser Sight||250 points|
|Match Grade Ammo||250 points|
- Tom Clancy's Splinter Cell: Conviction is the only game where the MP-446 is featured so far. It is also the first Russian sidearm to make an appearance in the game before the Makarov PM-B, the second Russian sidearm featured in Tom Clancy's Splinter Cell: Blacklist. Additionally, Kestrel, the first playable Russian Spy, is seen several times in screenshots with the MP-446.
- In real life, the MP-446's full name is the MP-446 Viking, and is made by the Izhevsk Mechanical Plant, a firearms manufacturer merged with Izhevsk Machinebuilding Plant/Izhmash in 2013 to form Kalashnikov Concern.
- Kestrel was known for having the MP-446 as a secondary weapon, despite operating a Five-SeveN in the cargo bay fight against Archer.
