Okay two things cause this (idk about your Gjally man I've never heard of that): 1. Explosive Rounds (previously mentioned) Getting a kill with the non-precision part of the explosive round won't trigger Firefly/Outlaw. 2. Perk Timers So basically when you get a precision kill it activates Firefly/Outlaw. Firefly is instant, but Outlaw lasts a couple seconds. The problem with this is that it doesn't reset with every trigger. Outlaw only lasts those (three?) seconds, and then it's done and you can trigger it again. So say you kill three things with precision shots. The first one activates Outlaw, and the next two are within those following seconds, and by the time you go to reload, Outlaw is no longer active and it takes the usual time. I hope that makes sense. This happens with Feeding Frenzy and other perks as well.
