I have been looking into defensive ammo for a few years now and, something I see discussed over and, over is over penetration. However, I rarely see anything about barrier penetration. I’m pretty much still on the fence on the subject of which is more pressing.
With the subject of over penetration my pondering is this. What if there is an innocent person behind the threat and, if so, should the shot be taken in the first place or, should you wait for a better opportunity?
With the subject of barrier penetration my pondering is this. What if you have an opportunity to stop a threat but, there’s some sort of barrier in between (for example a glass store front in a shopping mall). Will your chosen ammo not only penetrate the obstacle but, retain the ability to be effective against the threat?
