Hey, I discovered today that if you use Gyrfalcon's Haubrek and Collective Obligation it wont re-leech the volatility back into gun. After using the Void Leech perk on a beefier target before it runs out, you will only get back weaken. It works normally without Gyrfalcon's. After having some more time with this it can also be just coincidence between switching armor and volatility working the way it works.
