Hand mods weird for some reason

Okay so one of the first mods I got for h3vr was a hand mod. It was EFT_bear or something. Just yesterday I tried a diff hand mod and both mods for some reason when I grab things It just doesnt grab it properly. Like when I went to bolt an ak the hand clipped weirdly into it and when I tried to prime a pistol the hand STILL clipped weirdly. Is this just something with hand mods or is it a user issue?
