1. What's a Polish P-83?
2. When is it that the hammer doesn't touch the firing pin? Always? Or only when the trigger isn't pressed?
3. Does it have a safety lever? Is the safety "on" or "off"? Maybe the safety keeps the hammer away when it's "on."
4. Have you tried firing it? What happened?
5. From whom did you buy it? Didn't that person or store explain the gun's workings? Why not?
Got a picture?
