In TN, "'normal capacity" mags are legal. We have reciprocity with TX, so if you have a permit, you can carry here, concealed or open. No guns in state or national parks, gov't buildings, restaurants that serve alcohol (bill allowing this has passed, but is not in effect yet). A bill was also passed recently that will allow CCW holders to have loaded rifles and shotguns in their vehicle. I don't think it is in effect yet, so I would have all long guns unloaded and cased. If you don't have a permit, then legallly you have to have both gun and ammo locked in seperate places so that they are not accessible (ex, gun in glove compartment, ammo in trunk will meet this requirement). Most places are gun friendly. The one exception is that cesspool Memphis. Avoid at all costs.
