log off with a pistol inside a holster, when logged back in the holster goes from weighing "under 0.25kg" to "about 3kg" empty (once you remove the pistol). Also seems to be the case with gear inside clothing articles. As an example I had a splitting axe (which weighs "about 1kg" inside a pair of hunter pants - I then put the axe in a hunter backpack that weighed "about 1kg" empty and the total weight once the axe was added said "about 3kg"
