The gun further includes at least two stud cartridges each having a plurality of studs in side by side array and opposed end walls extending between first and second side walls. A first cartridge has end walls spaced a distance equal to studs having the first length. A second cartridge has end walls spaced a distance equal to studs having the second length.
