I think I found a bug in the animation for dual pistols (or at least the Disruptor Dual pistol Mk I) I'll include a link to a SS but basically the left arm is bent strait down with the pistol pointing to the left when crouched. The arm doesn't seem to animate but it's hard to tell. This doesn't seem to affect game play.

sorry if there is already a thread on this.
Edit: Strange... moving the item to a Boff reproduced it, but right clicking on a phaser pistol and choosing equip and then doing the same to the dual disruptors seems to have fixed it.
Edit the second: It's switching form a rifle to a dual pistol that does it.
