Sounds like the OP's talking about a 590SP. A used A1 still runs about $350, on a good day. I've had a 590 and it was great. Sold it for a 590A1, which I'm a lot happier with (speedfeed stock, ghost rings, 18.5" over 20", so less front heavy). Solid gun. It makes me hesitate on any other pump gun.
Generally speaking holes in anti-gun theories are called "facts."
