I've been looking for a one handed pistol animation for a Vault dweller gunslinger play though and although there is a one for revolvers, some that replace the deliverer with a different gun and animation and even one that makes laser pistols one handed but there isn't any for the 10mm or classic 10mm handgun. If there is one hidden under a strange name or if there just happens to be a talented animation mod author that is looking to add something no one else seems to have done yet then I would love to hear about it!
