in aiming. The greater amount of material in a long gun tends to make it more expensive to manufacture, other factors being equal. The greater size makes it more difficult to conceal, and more inconvenient to use in confined quarters, as well as requiring larger storage space. As long guns include a stock that is braced against the shoulder, the

when firing is transferred directly into the body of the user. This allows better control of aim than handguns, which do not include stock, and thus all their recoil must be transferred to the arms of the user. It also makes it possible to manage larger amounts of recoil without damage or loss of control; in combination with the higher mass of long guns, this means more
