The Holster Mod on Legs 'Gradually reloads your stowed weapons over time' is not functioning. I did give it 5 minutes while playing, but still no ... I tried these mods on multiple weapons, and on all three weapon types (kinetic, energy, power). Is this the right forum to give this info to?
Breech-loaded grenade launchers, rocket launchers, and bows are blocked from using holster mods due to having 1 shot in the mag.
They mentioned back when they were first introduced they did not want those weapon types to benefit from them, and when they changed from weapon based to element based holster they continued that behaviour.
Only exception to the 1 shot rule is Parasite due to it being a heavy drum GL.
