A training barrel having a central axis for housing a light emitting insert which includes an elongate member having a first end, a second end, and a first internal surface. The first internal surface extends from the first end to the second end. The internal surface includes a first segment which defines a first volume having a first cross sectional area perpendicular to the central axis, a second segment adjacent the first segment which defines a second volume having a second cross sectional area perpendicular to the central axis, and a third segment proximate the second segment which defines a third volume having a third cross sectional area perpendicular to the central axis, the third cross sectional area being greater than the second cross sectional area. The third segment may be configured and dimensioned to receive a light emitting insert and the first segment may be configured and dimensioned to receive a blank cartridge.
