I just bought a Rossi model 971 of of GunBroker. Looked really nice and I was looking for an inexpensive 357 mag with adjustable sight to carry as a backup when deer hunting or just as a carry gun when hiking in black bear country of Pennsylvania. Anything I should know about this gun? It looked like it hadn't been used very much as there was no drag ring on cylinder. This gun is in SS and only cost me $400 plus shipping.
