Passed these up when they were on the market by Ruger. Now I've got a desire to own one.. What's a NIB, Stainless, 7 /1/2, adj sights, and RCA (Ruger Collectors of America) engraved one worth?? Also if anyone has a NIB, Blue, 7 1/2, adj sights they would like to part with drop a line. East coast dealer wants $899 plus ship for the RCA item. Thanks
