I don't get the question. Of all the handguns I've carried or may be carrying now, I trust them all. It would be easier to name those I own that I do not have full faith in, and they do not get carried.
Some I own that truly impressed me after being purchased for defense, though, are the Bersa Thunder 380, the Kel-Tec PF9, the Bulgarian Makarov, and the Charter Arms Undercover (I have two of them, actually, from 1966 and 1987.)
