Worked fine with Drang, no issues. Tried it with a Xenoclast IV shotgun I wanted to pair it with, but Sturm kills did not refill the Xenoclast's magazine. Tried it with both partially empty magazine and completely empty. Swapped Xenoclast IV to Gnawing Hunger auto rifle to see maybe if it's cause of the ammo type as it uses the same type as Drang, but Sturm kills did not refill its magazines on kill either. Tested against Vex and Fallen at Cadmus Ridge in Europa, Drang used in EDZ against Fallen and Cabal, if it makes a difference. I was really looking forward to using Sturm, too, thanks to the buff. Edit: Just to add, I'm not talking about the Storm and Stress perk and the whole synergy with Drang. The Accomplice trait claims that 'Kills with this weapon fill the magazine of the equipped Energy weapon from reserves.', which makes it sound like it works with any energy weapon. I do hope that's the case and not the trait being poorly worded and misleading.
