When dualwielding the disruptor pistol and using the tricorder the left pistol is shoved into the forearm, so that the hilt is stuck in the wrist. Alas it remains there, even when the tricorder is gone. Sometimes the tricorder does not disappear too and you have both in the left hand.
No big issue, but something you may want to fix sometimes.
No, it is a male andorian (well, alien made to look like one for klingon empire) in brawler stance.
Not sure, if it is stance-related, since the right pistol is okay, only the left one, where I switch to tricorder from time to time, is a bit graphically bugged.
