Thanks Jim, BTW it's just Khanh. I will take all suggestions into consideration. I have cleaned the chambers, I will remove the ejectors and clean. I confident that the gun is tight and not off face. I will not have time to take the guns out again for a few weeks (family and work duties). I don't buy guns new so the majority of my guns have been used so this may be due to lack of use of the number two gun. I am not confident enough to do any work on the guns myself so they will go off to Jim Greenwood to look at.
