Signature Weapon

Signature Weapons are particular weapons associated with a specific Warframe or Companion, benefiting various advantages when wielded by its related character.

As of Update 24.6 (2019-04-04), Signature Weapons started to gain their own bonuses; before only the design and lore were related to their respective owner. The synergy varies from weapon to weapon and includes either a flat stat bonus (such as a flat Status Chance) or a new unique effect.

Notes

• Signature Weapons are also available in the market as part of their respective Warframe's Collection bundle including said Warframe and all the weapons associated. However, do note that not all Warframes having a Signature Weapon have their own Collection bundle. The Nidus Collection is the only exception as the weapons included aren't known to be his "Signatures".
• Unless stated otherwise, weapons featured in a Warframe's Leverian aren't known to be their "Signatures".
• With the exception of  Euphona Prime,  Tekko Prime, and all Primes released after  Octavia Prime, Prime Weapons released with a Prime Warframe in Prime Access aren't known to be their "Signatures".
• Exalted Weapons are not considered Signature Weapons.
