Your gun's relation of hammer to slide off center to the left looks very similar to mine. Have you shot it much? Are you getting hammer rub on the left lower frame when the hammer slams back in cycling another round from the magaine? Does the last round in the magazine flip up in the ejection port without entering the chamber causing a "live round stove-pipe" AKA BOB?
On the "Stovepipe Opinions" thread on this forum, the discussion for the BOB has centered around magazine problems (springs, lips, etc.).
