Trust is a huge deal with an EDC gun. You HAVE to trust it completely. That's why many of us put several hundred rounds of carry ammo through our guns before we depend on it. IMO (and many others) the .40 Shield simply can't be trusted. There are too many other guns that work well to have to depend on something that has a reputation for blowing up. That would always be in the back of my mind. Since I have other guns for EDC, the Shield would never leave the safe if I had it. No thanks!
