Sorry
I thought that the issues might be related.
And they well may be related.
There may be some very high gas pressure in the gun at the time of ejection. and with the magazine gone it could force the case into the path of least resistance.
If multiple .40 shields have blown up, and each with different ammo, then it would appear to be a flaw in the gun. Has anyone thought about a class action law suit against S&W? It's sad that their lifetime warranty is worthless since they NEVER admit any flaws with their guns. I own a .40 shield and I am concerned about the possibility of a kaboom as I have grown fond of having my hands...just a thought...
I didn't read every post but did you measure the length of the fired case?
To see if the case was a tad too long. The headspace is measured by the case length on most pistols. Too long of a case could cause an out of battery firing situation. This would explain the damage.
No, this is impossible. If the case is too long, the gun won't go into battery. If it won't go into battery, the gun won't fire. I've tested this myself and know that it's true.I didn't read every post but did you measure the length of the fired case?
