1. A powder actuated fastening tool configured to receive a powder charge strip, the powder actuated fastening tool comprising:
a barrel slidably movable from an open position to a closed position, wherein when the powder charge strip is received by the powder actuated fastening tool, in the open position the barrel is spaced from a powder charge of the powder charge strip, and in the closed position the barrel encloses the powder charge of the powder charge strip;
a charge advance apparatus including a rotatable ratchet including teeth engagable with the powder charge strip when the powder charge strip is received by the powder actuated fastening tool and configured to advance the powder charge strip relative to the barrel; and
an alignment member connected to and extending from the barrel such that when the barrel moves a distance, the alignment member moves the same distance, the alignment member configured to move relative to the rotatable ratchet when the barrel is moved from the open position to the closed position to ensure the powder charge of the powder charge strip is in alignment with the barrel.
