So I'm not sure if it's been reported yet, but whenever Connor is wearing a special outfit (that being anything but the default or a color swap), his pistol in his right holster changes to the Pitcairn-Putnam pistol or the Scottish pistol if you own that like I do. With all the new and returning outfits to play around in, I can't be the only one upset that this bug has made a return in a fully remastered and reworked game, especially considering the time since its original release. Hopefully this will get patched out sooner than later, because it's really putting a damper on my experience with the game like it did in 2012.
