Clear the gun, pull the trigger and keep it that way. Then rack the slide back (with the triger still pulled) and let it go forward gently. If it does not align completelly with the frame, you have an expired recoil spring. The poroblem is that when you are shooting, your focus is on the sights, not noticing (if that is the problem) that the slide does not reach all the way to the front of the frame, hence causing the light strikes. If that's not the problem, it is probably amo related. Check that!
