An explosive charge driven fastening element setting gun includes a barrel and a rotatable drum-type magazine both axially displaceable within a housing. As the barrel is displaced into the firing position it is arranged to seat into the aligned one of a number of bores in the magazine. A location on each of the axially extending surfaces of the barrel and magazine spaced axially from the location of the other is disposed in clearance-free contact with a surface within the setting gun while the remaining axially extending surfaces of each are spaced radially from the juxtaposed surfaces in the setting gun to provide lateral movement to assure alignment between the barrel and the bores in the magazine when the barrel is moved axially into the firing position. |
