No, and a very poor choice for any type of serious carry use.
I don't recall the specific accuracy of the thing, but it wasn't good enough to impress me sufficiently to remember.
It was one of a handful of BP derringer-types I tried, none of which were all that impressive in either accuracy or power, although that Philly Derringer was at the top of the bunch in power.
Still totally impractical in the face of so many better defensive choices in about the same size & bulk.
It's a fun toy, but today that's ALL it is.
