+# Trivia
+
+- Servant is the only weapon to be dual wielded. Also it is the only weapon that the player does not use the knife when doing melee attacks because the player already has both hands holding the guns when they are daul wielded.
+- Hitman is the most powerful pistol, equating Impressor for power, but rarer to get.
+- Ordinator normally has 12 rounds, but some ammo crates and drops have extended magazines of 20 rounds, making it the most number of rounds of any pistol.
+- Operative and Tactician are basically the same (MP5A5 and MP5KA1 respectively), but the former packing more power and a faster muzzle velocity yet has a slower rate of fire, while the latter has less power and slower muzzle velocity but faster rate of fire. When the player acquires both guns, their magazines can be interchangeable.
+- Specialist can have scope attachments that can increase the firing range of the player. It also has the fastest rate of fire among automatic guns.
+- Impressor is the only shotgun in the game.
+- Militant is more likely to appear in map crates.
+- Paragon is the only gun in the game with a grenade launcher.
+- Some enemies are equipped with M1911 pistols, but these cannot be retrieved by the player.
+- Enemies equipped with the Servant do not wield them dually.
