Selling a barely used (less than 50 rounds) Rosi RM66 revolver for $400. Original cost was over $500 (which includes replaced front sight). The front sight was replaced with a XS night site that cost around $80. Some background history: the gun was returned to Rossi for repair because the gun would lock up every time or every other time after firing a round (used Freedom Munitions .357 mag rounds). Rossi found no problems with the gun and tested it with 12 rounds of PMC 357 mag, and 12 rounds of Federal 38 spc. Not satisfied with these findings (my range experience was quite different), I ordered another evaluation. They still concluded that there was nothing wrong with the gun, and the gun was returned to me. After receiving the gun, I went to the range, and the gun would again lock up after firing Freedom Munitions .357 mag rounds. Then I shot .38 spc rounds from Magtech and had absolutely no problems. In summary, I believe Freedom Munitions ammo was the source of the problem all along. There is a slight marring of the barrel when I tried so desperately to remove the front sight pin (see photo). The reason I’m selling the gun is because I can’t shoot accurately with the gun, and I only keep guns that I can shoot well. Cash only, no trades. Must present Tx id and sign a bill of sale. I live in the Clear Lake region of the Houston metroplex.
