About two but most of the time, I use nylon knee socks that I spray with silicon. That way the buttstock is protected and I still keep the muzzle end open. Not entirely sure why you ask, but, in or out, I use these. I also use them inside a hard case, for additional protection. ....When you guys put your long guns in your safe do you put them in a silicone impregnated gun sock ?
They make them for handguns as well and again, I just put them in "regular" nylon socks that I spray with silicon lube. ....I have seen the ones for rifles and shotguns but not for hand guns.
