I was seriously considering the CP1; it's a pretty little thing, and I've been looking for a 9mm backup.
BUT, it has an extremely limited service life. Basically, when your mag goes dry, you throw it away.
OK, that's an exaggeration. Vektor SA says it's good for, IIRC, 5000 rounds. It's literally a carry-lots-shoot-little gun. Based on this short lifespan, I can't recommend it.
