which ones

almost all of them, the luger's barrel is at 30° to the right, the tommy gun's bullets are 30° to the right (in the mag), one of the revolver has it's cyllinder completely wrong, the PPK's mag clips through the grip on the left and a lot of other stuff

for me at least

found out this is tied to the lewis gun from my tests. can be fixed in game by bringing the lewis gun down to 25 or empty then switching without reloading.

Yeah it's the lewis gun problem idk why, any other weapon doesn't give that dumb effect

Probably something has to do with that spinny drum magazine

i have te same issue, when npcs holds any weapon, for example a lee-enfield, i can see the models of the rounds and striper clips floating a few inches behind the gun

I'm currently having at least half of the guns have SOME PART of them at a 90 degree angle.
In the case of the Welrod, the handle itself is outright clipping through my hands.
On the 1917, the cylinder is sideways, but the bullets are oriented normally.
On the Webley Mk.IV, the trigger is sideways.
The PPK has a floating sideways magazine.
The Luger, the entire barrel assembly is sideways.
M1919, the entire belt runs down the barrel of the gun.
