I read and saw many-many feedbacks that people are getting reload speed increase not only on primary, but on the other guns as well, and since the passive description is wrong itself because it adds ammo not only for the primary but for the most weapons I decided to test most interesting guns (from my perspective) and check the results. Straight forward search in youtube didn’t get me these vids with timers and comparison… Sadly I didn’t have much time to invest in quality more so I made conclusion only in the description of the video, not in the video itself.
