It has no lock and is 6-shot,I traded a tuberware Glock G23 40sw even for it. Wow now this 357 snubbie is a ccw dream for pancake OWB ware. A simply rugged pancake fits like a glove and carry very good for ccw. I like this pistol allmost as much as the m19 snubbie. Very accurate and smooth. No MIM parts or lock garbage. I date it 1990ish.
