When you say beat up I take it as not in cosmetics but play in the cylinder. How many rounds through the gun? 686's are tough guns to shoot out. Questions: does it miss fire a lot? Does it shave lead or spit to one side or another? I have shot out one gun a model 66 and adjusted the cylinder end play three times to the point where the gun was not safe enough for police work anymore, but it was still usefull. I would send it back to S&W and have them go through it, they will bring the gun back to spec, probable for nothing including the shipping charges.
