Best way to find a shotgun

I am looking for a used Beretta ultralight 687. Anyone know the best place to fing one?

Try the firearms classifieds or auctions at The Gun List. (to make it easier to remember, http://www.gunlist.net goes to the same address)

We do a lot of gun sales on the internet, and our favorite sites are:
http://www.gunbroker.com (but watch yourself, because there’s no 3-day inspection period mandated by the site in case you get screwed.
http://www.auctionarms.com There is a 3-day inspection here, supposedly, though if a seller wants to be a jerk, he doesn’t have to send your money back…
http://www.gunsamerica.com This is a classified listing, so things generally go higher than in the 2 aforementioned sites. It’s searchable, though, and you don’t have to worry about staying up 'til 3 a.m. in case some jerk outbids you.
