The .40S&W is a better choice for self defense than 9mm. A 165 grain bullet is a better round for the .40S&W cartridge. However, that article is old and has some misinformation in it.
First, the Glock no longer has the so called "unsupported" chamber. They have updated their design and now the chamber is as supported as any other gun. Second, the brass does not contain the pressure, the chamber does. So, for the author to suggest that 10mm brass is designed to handle higher pressure than .40S&W brass is a misnomer. The brass case, for any cartridge, is there to hold the components together. It's the job of the chamber to contain the pressure and direct it down the bore.
In the case of the OP, it seems that he had an out of battery discharge. If that's true, the caliber is irrelevant because the case cannot contain all that pressure.
Thanks for clearing those points up.
I was aware of the design change made by GLOCK so I assumed that the unsupported issue with them was put behind and corrected.
As for the brass comments, how silly of me to think that the brass is the only component that retains the firing pressure. I should of realized that the brass is contained in the firearms chamber and that is what contains those forces. Now if the firearm manufacture designs his chamber close to the mininum then there could be problems with over pressure ammo.
