Male Norn - Krytan / Magitech armor
That picture features a character on an incline. Things will clip when that happens, regardless of race and weapons.
It clips whether it’s on an incline or not. Maybe I should have chosen a better picture.
It does not clip on the other races since their stance is different. Also the weapons do matter. When wielding pistol/pistol you hold them higher compared to sw/p or d/p.
