Fellow has a one owner Delta 10mm blue in good shape. A Gold Cup I might add and made in '91. It is lets say 95% or maybe better finish wise and all original. He says that it has had about 1 to 2 thousand rounds through it. He is looking to get $1,000.00 for it. Is that a fair asking price under the circumstances ? How many rounds should that gun be expected to cycle before it is "shot out" ?
