8/9/22 - This is a mint Colt Trooper revolver that was manufactured in 1966, so is C&R eligible. The Trooper was developed as medium frame alternative for law enforcement that could provide ideal handling characteristics for .357 Mag or .38 special. It has a four inch barrel and chambered in .357 magnum. There's just a tiny hint of muzzle wear, and extremely thin roll mark on cylinder. Perfect mechanics and mint bore. Minty grips, too.
