Guardian of my hand?
I loved the Guardian, in the store. I bought a 32 version, prior to the newer 380 size.
I soon found out that I was carrying a rock in my pocket, awfully heavy.
It barked sharply and often left a bit of blood on a finger. Overall, it hurt to shoot and practice, and as said before, you needed to be especially firm with the grip to ensure reliable ejection.
I sold mine, went to a really ugly Kel-tec, that was more reliable, easier on the hand, lower cost, and half the weight. Since it stays out of sight, I've only gained effectiveness for what it was meant to do.
