From Destinypedia, the Destiny wiki
Crimson is an exotic kinetic hand cannon that appears in Destiny 2 as part of its Curse of Osiris expansion. Built in the same fashion as the notorious Red Death Pulse Rifle, Crimson fires in three round bursts, and regenerates health for the user after a kill. Additionally, the main perk for Crimson reloads the weapon instantly after getting a precision kill.
According to official Vanguard policy, this weapon does not exist.
"This is crazy! You don't need this thing. I can heal you; that's my whole job."
To upgrade to the full Crimson Masterwork, the player must score Headshot Kills with Crimson. The fully upgraded Masterworks grants the Weapon +30 range, bringing it to 100.
