I was at the local gun store today. The guys there know I like older metal framed pistols, and they told me they had just received an interesting one for sale that they didn't even have a price on yet. The employee brought out a worn 659. The gun wasn't in horrible shape but it looked like an ex-LE gun or something that had been carried a lot. Obviously without pictures it's difficult for me to ask what it's worth here, but would $3-400 be decent assuming it's free from rust and the bore is clean? Also is there anything I should specifically look at when examining the gun? I'm familiar with Gen3 S&W pistols but not so much the Gen2s.
