I traded for a nice 669 today at a local pawn shop. They had it priced at $289, just one mag, no extras. The low price should have been a tip off to me.
I got it home and broke it down to clean and I have to say, it is the dirtiest used gun I have ever owned. The dirt was so caked up on the slide rails I was using my fingernail to scrape it off. The bore didn't look bad. This may have been owned by someone who had a boresnake and figured that was all the cleaning it needed.
It's too late now for me to get out anywhere and shoot it, but I'm sure it will do well. It's nice to have another S&W in the collection.
