Saturday Night Special? Why would ANYONE use a term invented by the anti-gun people?

As for the Raven, they had a pretty good reputation for reliabilty during the first couple of years of production. They share the same weaknesses of all small, blowback, striker fired handguns. IfI couldn't afford anything else, a Raven would look like a decent handgun for the money.
BTW, I've seen some PPKs and PPK/s that wouldn't feed three rounds of ball in a row. Doesn't mean they are all bad, just as the one raven doesn't mean they are all bad.
