Smith & Wesson M&P 340 .357 magnum revolver LNIB. The M&P340 has the carbon steel cylinder, no warning as to bullet grain weight, and XS Tritium front night sight (13.3oz unloaded). Hardly notice you're carrying it. Fewer than 50 rounds through it. Hogue grip added to lesson the bite. Original grips, box and paperwork included. Asking $650 FTF.
As for trades, I may be interested in a T/C Encore, .357 lever action rifle, Winchester 9410 w/ tang safety.
Plus or minus cash depending on deal. Maybe others I won't know until you shoot me a PM.
