While browsing through the BIFs I found in the PlateCav.BIF an animation of firing a pistol. The pistol is even provided on the frames. Don't know if this can be of any use to anyone, but it's a free unit It needs the correct weaponpositioning but when you're done, and you'll have a very charcterfull late light cavalry. Might be worth a shot (excuse the pun)
