does anyone know how to fix the holdtypes?

because i like using my chasecam addon for RE style 3rd person, but sweps before that update are all pistol holdtype. Is Garry trying to fix that? or can someone else? and another thing, does anyone know if the two handed models for the pistol and AR2 are seperate skins? i have a beretta model for my pistol and i have the 2 handed pistol as well but it doesnt work (i know where to put files so im not doing something wrong there)
