Today I was using my Kimber commander size 1911 (.45ASCP) and I noticed several times an odd failure to fire -- several rounds form the mag would fire fine, then about halfway through the magazine I would pull the trigger and the gun would not fire. If I tapped the magazine up (without any slide racking) it would then fire. It felt like the firing pin may not be hitting with enough force.
Why would tapping the mag up improve this situation?
