I had a Bond derringer in 9mm ... if you're buying it for SD, don't ... way too heavy to justify carrying with only two rounds, hard to cock, slow to reload, hard to be accurate at SD distances with it ... fun range toy, I finally traded it for something I wanted more ... I carry a Kahr PM9 or a Smith 637 -- both are lighter and carry way more rounds ...
