I'm wanting to dip my feet in the large caliber revolver pool, found this available locally........., NIB Unfired Stainless Ruger Vaquero 44mag 4 5/8" barrel (Old Model) Heavy frame, box papers and all for $500. Seems like a good deal to me on a very nice looking pistol - any advice, warnings, or anything else I should know about this revolver before jumping in the pool?
