I have fired any and all available ammo from my Governor and have had 1 problem. It was loading steal 45acp ammo in the moon clips and that causing a tight fit when trying to load the moon clip in the cylinder. That was solved by just using brass case ammo. Even dirty cheep brass was no problem. As far as the 410 shells, all fired smooth as glass. My wife loves the gun and she fires it well also.

There are some pretty bright guys here on the governor threads that can answer the mechanical issues. Just sit back and read/learn. The governor is a great gun and don't let anybody try and tell you different. If there IS a mechanical/part issue, S&W will fix it. Follow through with your investigation regarding this issue. You need to find the answer.
