Watch this Forum daily. I found a 4" 617 being sold within an hours drive and didn't hesitate. But I stress checking daily. A popular gun at a fair price will not last long. And as far as ammo, the Federal Bulk Packs are the cheapest, shoot well and are quite clean. FWIW, Cabelas has the 375 pack on sale for $ 9.99 each and 50 cent shipping on orders over $ 99.00.
