if i were you , and i were to purchase any of those , even if they were still shooters , i'de put them away as collector pieces. and yes , i like to shoot the old ones , especially the older calibers.

as for safety issues , your best bet would be if you were to purchase one of the listed firearms , would be to have it fully examined by a competent gunsmith , there's just so many things that could be damaged or just worn down to the point of rupturing under the pressure of a recently fired round , that cannot be seen by a mear eye inspection. another thing to think about if you want to fire one of them would be reduced power/pressure loads.

hope that helps buddy
