perhaps not very tactical,
but is a decent way to recycle and reuse old sweaters/gym suits: with a scissor, needle and thread, or a sewing machine, it is easy to make a cloth tube of the size suitable for any weapon, long or short.
the weapon, oiled, ideally should be stored muzzle down, so that the oil cannot seeps inside the wood of the stock,
with the crown protected by a rubber stopper, such as those used for the legs of the chairs, but with a little hole in the center, for obvious reasons.
the wool does not retain moisture and, if impregnated with gun oil, it works even better_
in my opinion wool would be the most suitable material but fleece and even cotton did not give me problems,
if sprayed with oil or even silicone for car dashboards.
the elastic bands used for the ponytails are perfect for tightening the folded ends_
