Afternoon, Sturm: Does not fill energy weapon mags as intended. It works fine with Drang, though the perk states it fills 'the magazine of the equipped energy weapon'. This is how I use it personally and have used it in previous seasons. Ex: Fire with 180 energy HC, kill with Sturm to fill energy HC mag, repeat. Sturm is in a great place since the move to 120RPM, this last fix would cement it in my daily loadout. Thanks for takin' the time to read. -Solo
