My 1st legendaries, both obtained through purple drops. Partially upgraded, so stats aren't final:
Cryptic Dragon Upgrades:
3 scope upgrades
5 damage upgrades
Take a Knee: Gain bonus accuracy while crouched
Explosive Rounds: Volatile payload explodes on impact, dealing a porting of the weapon's damage in an area.
Lightweight: When held, this weapon grants +2 character agility
Armor Piercing Rounds: These iridium-core rounds overpenetrate targets. Their mass slows down weapon handling.
Fair and Square Upgrades:
Headseeker: Body shots with this weapon increase precision damage for a short time.
Hammer Forged: Improved range and accuracy
Lightweight: When held, this weapon grants +2 agility
Snapshot: Aiming this weapon is incredibly fast
Reactive Reload: Reloading this weapon after a kill grants a damage bonus for a short time
3 Scope upgrades
5 damage upgrades.
I'm also chasing down and exotic hand cannon, although I don't use them. Going to disassemble and see what I get, hopefully ascendant energy and shards. I'm on bounty #2 of 4:
