Im surprised I havent seen more people mention this one, the Grenadier Gauntlet is suppose to have 5 rounds. The weapon isnt in a strong place already and could use some buffs anyway, might as well correct this issue and give it the 5th round it deserves.
Complete side note, but why do all the ogryn weapons use the LOD version of the weapon for the icon in the player inventory? thats another bug ive noticed
