Is it a good gun?
I try never to bash someone else's gun, but there is a class of firearms that are best suited for paperweights and shadow boxes. They usually have RG or FIE on them.
Many of these guns had a frame made of "pot metal", a zinc alloy. With a low melting point of 786 °F, zinc is often alloyed with other metals including lead, tin, aluminium and copper. This was melted, poured into a mold, and barrels usually had a thin steel liner.
The 1968 Gun Control Act banned import of certain guns (Saturday Night Special was the term) that, among other things had a low melting point. Many of these were made in West Germany, and after 1968, became blank pistols.
Many of these become unsafe to shoot due to timing problems, or simply break.
